RE: TV tire life

I had 7 year old Michelins on my truck with only 15,000 miles. Parked in garage at all times when not in use. I had a blowout on I-40 just east of Barstow, CA that did $3500 damage to my rear quarter panel. Not an experience I want to have again. Discount Tire will not fix a tire over 7 years old if it has a nail in it so take that as a guide. I would not go over 7 years without replacing. I had 2 good looking seven year old Michelin tires explode on my truck several years ago. The truck was technically totalled. I called Michelin to find out what was going on and quality manager for the US told me that nobody in their right mind would keep a tire over 6 years and refused to take any responsibility for the damage. Those were the last Michelin tires that I will ever own.

RE: Tesla Semi truck unveil & test ride set for Oct 26th !

The new government with focus on climate change and alternative energy sources should take up Elon's offer to electrify the whole country with solar energy by providing for it 100 miller x 100 miles site to put it on.I've read some reports that are wondering about the effect of that much heat produced by those black solar panels. It's my understanding that they're about 20% efficient so it would seem that they will radiate quite a bit of heat that would otherwise be reflected, since they would tend to be located in areas of normally high albedo.. Just a thought. Black color absorbs heat it doesnt reflect it ! And solar panels are way more then 20% eficient https://youtu.be/c-auRHKq2-A"Black color absorbs heat it doesnt reflect it !" Uh, that's what I said. Everything I've read about solar panels say the same thing: 15% to 25% efficient. I was surprised to learn that at current efficiency using solar panels can actually lead to local warming due to the amount of solar radiation that they absorb. I had assumed that by converting some of the solar into electricity which is carried away carried away through wires they would cool the area. But, it turns out that at least is some areas the natural environment reflects more energy than the current panels convert into electricity. This leads to the natural environment being cooler. As with all tests your results may vary but this is an interesting point to consider. It would be interesting to know what efficiency rate is needed for solar panels to be temperature neutral in various environments. Solar panels in the Sahara would raise temperatures 2.5 degrees C or about 5 degrees F with 50% coverage is a pretty serious temperature increase.

RE: F150 w EcoBoost 2.7

If you go back to the link that I provided on page 1 of this thread you will see that even the diesel is not rated for 80 square feet of frontal area on a bumper pull trailer. You won't feel it as much on the diesel due to the extra power and torque that it has but the engine still isn't rated for it and the drag will still make a huge dent in his fuel economy. Some of this is based on the presumption that the trailer has a full width rectangular front end with square corners but the op hasn't given us any details other than his fuel economy which seems to be pointing that direction. For an interesting reference point, my 23,000lb diesel motorhome is 11ft tall and 8.5ft wide. However, it has a rounded front end with very well rounded corners and it will turn 11.5mpg at 65mph without a trailer. Upper 9's with a loaded 3 horse trailer behind it. But the trailer is riding in the slip stream of the motorhome and really isn't very noticeable back there. That is with a Cummins 6.7 detuned to 300hp and 660lb-ft of torque. Not much get up and go but it does give remarkable fuel economy for a rig that size. The weight doesn't seem to have much bearing on the fuel economy, at least on the highway.

RE: F150 w EcoBoost 2.7

A lot of informative post. Turbos spending most of the time spooling and sucking fuel. I'd highly recommend you look at the GVWR of your trailer as that's going to be much closer to it's actual weight vs UVW or dry weight.....unless the 6000# you quoted is confirmed scale weight. Example: Our current trailer has an UVW of 6120 and an GVWR of 7740. Trailer scale weighs at 7620 with just the wife and I. Bottom line is the 2.7 would certainly be considered a marginal tow vehicle with that weight, doable perhaps. Trade in value is ridiculously good in present market if you wanted to go that route. If you have a good local Ford dealership, consider a 7.3L and put marginal to rest which will also allow future upgrades in trailers. Stay safe. The issue isn't the weight. It is the air drag on a 10' high 8' wide trailer. The 2.7 will easily handle the weight. Any engine will struggle with the air drag. He really needs to look at ways to reduce the air drag.

RE: F150 w EcoBoost 2.7

Your problem has a lot to do with the frontal area and that will carry over to any truck, though you are working the 2.7 a lot harder than it was meant to do continuously. The main way that the F250 will help you is if you get the 48 gallon fuel tank. All Ford pickups are rated for 60 square feet frontal area bumper pull, 75 square feet with a gooseneck. The reason for the higher rating on the gooseneck is that it is closer to the cab and gets less direct wind on it. When my daughter switched from a bumper pull horse trailer to a larger and heavier gooseneck her fuel economy went up You would probably do well to get a camper shell that rises up in the back to maximize air deflection around the trailer. Or a gooseneck trailer with some aerodynamics up front. See page 16 of the towing guide: 2021 Ford towing guide. Are boats are probably at the 60 square foot frontal area but the pointed bow and raked windshield help reduce drag.

RE: F150 w EcoBoost 2.7

How much frontal area does the trailer have? How fast are you towing? I get about 12mph towing my boat with my 2016 3.5EcoBoost. The boat is 8ft high and 8ft wide. Not as heavy but the wind drag is the most important element for fuel economy. My brother tows a similar rig with his 2017 2.7Ecoboost and gets quite a bit better fuel economy than I do. I get 8.5mpg towing an 11,000lb equipment trailer. You should be doing better with the newer tech and the 10 speed transmission. My experience with a diesel is that it gave about 30% better fuel economy pulling my equipment trailer.

RE: This should help with future GM EV tow vehicles.

Looks like the coal and gas powered power plants will be running at full capacity. My electric car is charged by TVA which is expanding its nuclear capability and has a significant hydro capability too. My son charges his most days from his solar panels which he saved from going to a landfill.

RE: Tires, lol

No one can answer that question. The weight of your RV and the loads you plan will make the decision for you. There really aren't any "don't buy this tire" out there so as long as you keep the same brand of tire with the same load rating on each axle, the brand could be different on each axle. I like Firestone (owned by Michelin) as well as Michelin and Goodyear. Others have had success with nearly every brand out there including the Chinese brands. I like Firestone too but they are actually owned by Bridgestone which is good since I don't like Michelin wikipedia Firestone Bridgestone/Firestone also makes Fuzion

RE: Would you switch from Class A to Travel Trailer

As I continue to pounder on this decision, I want to thank everyone for this great feedback. In my research I have found that while a Class A may be more expensive and difficult to maintain, it could make a big difference when traveling with dogs. I think this matters more than I thought. We continue to sleep on this decision :-) MC The dogs are one of the main reasons that I have a class A. With a built in generator and auto gen start I can be reasonably comfortable leaving them in the coach in any weather. Also, everyone but the driver can get food on the road, use the microwave oven, use the toilet and cater to the driver's needs. Sometimes I pull a toad, sometimes a boat, sometimes a horse trailer. Pulling a TT and a boat behind a truck doesn't seem to work very well. It all comes down to what your needs are though. I do love being able to drive 4 hours, boondock for 3 nights and drive back home without stopping for fuel.

RE: Door latch

I can't give you a review yet but I have one of these in a box to put in. The posted reviews are mostly good. Electronic door lock with remote My original Tri-Mark latch broke several years ago, trapping us inside the RV. The replacement looked just like the old one on the outside but the guts were completely different and it seems to be holding up better. My only reason for replacing it is the get the convenience of the digital keypad. The RVLock has 5*5 combinations, or 3125. I tried a combination lock years ago and was dismayed to find that it only had 4*4 combinations, or 256. Besides that it didn't do anything well. I ended up throwing it away. I recently saw an RVL in use that had obviously been there several years and the owner really liked it.

RE: Ford as a tow vehicle

To get that high tow rating on an F150, you have to have the HDPP and those are not on the used car lots. You might find a MaxTow equipped one and that's better, in that you get a bit more GVWR on the truck, but forget about towing an RV of that 'tow rating' size.. I have a 13 F150 MaxTow Eco with #7700 GVWR and I'm towing a #7000 loaded TT and that's about all I want to tow comfortably with it. It can tow more, has tons of power, but just for the shear comfort level of towing, it's all I want to tow with it. You will run out of payload long before you reach any 'tow rating'.. So, choose wisely.. The newer Fords all have the auto engine start/stop feature.. No cylinder deactivation, and you can turn off the start/stop, but have to do that every time you start the truck.. To get the old 6.2l in an F150 you have to get the Raptor or a Platinum or higher trim level probably some 5+ years ago.. But, they don't have any payload left, so won't do you any good anyway.. Good luck! Mitch https://i.imgur.com/XG8H0uzm.jpg?1 The auto engine stop is deactivated whenever trailer lights are plugged in so it is a total non-issue when towing. And you can rig up some extra lights to use when not towing if you want a simple defeat mechanism but you really are better off just getting use to it. The 3.5 turbo has a lot more torque than your 5.3 does and it won't lose torque in the mountains like a naturally aspirated engine does. I think that it address the issues expressed by the op. The 3/4 ton gasses would be a little more solid towing but would actually have less power, especially in the mountains, and would consume a lot more fuel when not towing. I regularly tow over 10,000lbs with my 2016 and think that you would be happy with one if you don't need the payload of a 3/4 ton. 2018 and newer models will have the 10 speed tranny which seems to be a nice improvement while towing.

RE: 3/4 ton diesel vs. gas

You know that hill you go up now at 2000 RPM in your diesel? It will be at 5500 RPM in the gasser. If you like to hear a screaming motor, get the gasser. If you like the easy rolling diesel, pay for the repairs and drive it for another 10 years. A friend of mine just pulled his 35 foot trailer with a diesel for the first time last week. His first comment when he arrived at the campground was, it didn't even work coming up the hill. This is a man that has always modded his exhaust to get the loud V-8 sound. He said "No more screaming motor and stopping for fuel every 150 miles." What the F? That so called "screaming" motor is working at its designed parameters. Only the uninformed would refer to a working symphony of parts working as designed as screaming. I'm sure by "screaming" he means the deafening noise, not that the engine isn't doing what it's supposed to. Call me 'uninformed' if you like, but noise is noise -- and it's not a pleasant sound. I haven't driven a 7.3 but every time that I have updated vehicles I have noticed a significant drop in engine noise, especially at higher speed. The assumption about load noise from a high revving engine probably isn't more true than the assumption that diesels clatter and wake up the whole campground when you come in late at night. My experience has been that a gas burner burns about 20% more fuel than diesel. Some of the new trucks come with a 48 gallon fuel tank which should be plenty for anyone's bladder to fill up before the tank gives out. Even with my old 460 loaded to the hilt I could go over 300 miles between fuel stops with the two 18 gallon tanks which was always adequate. My main concern for the op is that the truck in his sig is a Chevy and if he stays with Chevy he will probably have to use premium gas and that would be a huge roadblock for me.

RE: Dually tire replacement upcharge

I agree with the op's point that a dually only has half as many lug nuts per tire as a SRW vehicle so in fact he should have gotten a discount.

RE: Tesla driving across Canada in 74 hrs

Random thoughts about battling lithium-ion battery fires--- * The recent Tesla accident near Houston, firefighters used at least 32,000 gallons of water to extinguish the flames. Firefighters at the scene contacted Tesla for advice on how to extinguish the blaze and were told just to let it burn out. * 32,000 gallons of water weighs over 132 tons. * Average fire truck holds only 500 gallons of water. * Tesla's Emergency Response Guides excerpts-- FIREFIGHTING USE WATER TO FIGHT A HIGH VOLTAGE BATTERY FIRE. If the battery catches fire, is exposed to high heat, or is generating heat or gases, use large amounts of water to cool the battery. It can take approximately 3,000 gallons (11,356 liters) of water, applied directly to the battery, to fully extinguish and cool down a battery fire always establish or request an additional water supply. If water is not immediately available, use dry chemicals, CO2, foam, or another typical fire-extinguishing agent to fight the fire until water is available. Battery fires can take up to 24 hours to extinguish. Consider allowing the battery to burn while protecting exposures. Houston, think we may have a problem..... OTOH, I have seen liquid fuel running down the street burning. And seen the fire start a block from the wreck. If the battery stays in 1 place that could be a plus. I can remember several deadly and/or destructive truck fires. Every battery powered vehicle on the road helps displace another tanker. The fear of the new is almost always worse than the few of what we have lived with all of our lives, whether deserved or not. When reading the instructions for dealing with a Tesla fire keep in mind that virtually consumer or pharmaceutical has warnings about the product causing injury or death. In California anything cooked on grill has to carry a cancer warning.

RE: Operational problems with new diesel pickups

Motorbiscuit.com shared that in a recent survey cars.com survey both GM brand heavy duty trucks had the lowest reviews on new customer satisfaction. Motorbiscuit Before anyone gets too excited please remember that lowest is relative and the competition is tough, leading to this statement: "The 2021 GMC Sierra 3500HD actually earns a total of 4.5 stars overall. Consumers give this truck 5 stars in the performance category. In fact, it gets 4.5 in all the other categories except one. For reliability, the 2021 GMC Sierra earned only 2 out of 5 stars." Chevrolet didn't fair quite as well: "The Chevrolet Silverado 3500HD is the one truck that actually has a pretty low overall score of 3.7 stars. Owner reviews tell tales of issues soon after purchasing the truck. Even with very low mileage, the 2021 Chevrolet Silverado 3500HD is in and out of the shop with a frequency that’s angering buyers."

RE: Cummins/Tula dDSF (diesel Dynamic Skip Fire)

If the 4.5l engine is expected to do the work of a 6.7l it will be interesting to read what they did to ensure long life. The 4.5L is pushing a 175kW(234 mechanical horsepower) electric motor in a hybrid setup so it is not primarily the diesel engine that is doing the work. Very similar to a diesel-electric train setup. But all of the power still originates with the diesel engine unless there is a plug in battery pack that I am missing.

RE: Tesla Semi truck unveil & test ride set for Oct 26th !

This thread now four years old and still no semis. Yah but it’s been a heck of a ride. :).So to speak. :) Production is coming as soon as the Texas plant is built and it is going up fast. Tesla has totally new factories going up not only in Texas but also in Germany and what could be considered one in China. Plus they are in discussions with the governments of India and England about building factories in their countries. Tesla is easily the fastest growing auto company on the planet. Meanwhile the Semi has been refined in the 4 years since it was originally displayed and several new prototypes are on the test track. Communications with customers has been increased and it sounds like deliveries will start fairly soon. Latest semi update to customers.

RE: Cummins/Tula dDSF (diesel Dynamic Skip Fire)

"Diesel engines already emit less Co2 than an equivalent gas engine" Regardless of the fuel there should be a strong correlation between fuel consumption(or savings) and CO2 output. Those statements may have come from different trucks too. If the 4.5l engine is expected to do the work of a 6.7l it will be interesting to read what they did to ensure long life.

RE: Cummins/Tula dDSF (diesel Dynamic Skip Fire)

A 4.5l in a class 8?! Or have mixed in information from different tests? Either way, I like the concept for a motorhome if the 4.5l can be made quiet enough to be acceptable for use a generator in a campground. Having separate engines for propulsion and generator in a motorhome complicates a lot of things and adds a lot of weight. I spoke with a high level person at Thor recently and he told me that there was something like this in the works. The article doesn't mention use a hybrid but could add a lot to the versatility of the drivetrain. I don't understand how they increased fuel economy 20% but only reduced CO2 emissions 5% though.
