RE: Newbie with general tow questions

You don't have the tow package so you can install wiring, and a hitch and tow a 2000 lb trailer. Because the trailer you are planning to get is a pop up and will have very little wind resistance I would think you could cheat a little and pull a 2500 lb fully loaded pop up.

RE: SWR 5th wheel towing

We towed a 36 foot 4 slide 15,600 5th Wheel first with a 2500 short bed gmc 8.1 gas with a manual slider hitch and it handled it ok , then towed that same 5th Wheel with a Chevy 3500 diesel DRW long bed ext cab and it was a dream to tow ! It always felt like there was more than enough truck and was rock solid towing , Really depends on how often and how far your towing . If your doing a lot of traveling you may feel better with the long bed DRW , from experience there is no better setup but cost can’t always be justified. I have always had a Toyota echo that’s now about 20 years old for a daily driver when I was working so having the bigger truck has never been a problem , currently have gone to a DRW gas setup for our current TC which has also worked out well , you will never hear or read about someone having to much truck!! Good luck and safe travels . I have a highboy I can tow behind the Peterbilt as well as a tandem dually gooseneck equipment trailer I can tow behind my SRW. For loads under 30,000 lbs I always choose the pickup over the Peterbilt. So I would rather be a little over loaded than than way underloaded. I think the SRW 3500 series trucks are perfect for pulling up to about 16,000 lb RV's.

RE: 2017+ Powerstroke 6.7 Fuel Filter

I certainly don't have any interest in ordering and stocking spare parts that I will likely never use. I might change the primary filter once in the time I own a truck but it's unlikely I'll ever change the under hood filter. Remind me never to buy a used vehicle from you! I own about 20 diesel engines and have for many years A few of the engines I currently run I've owned for over 20 years. I've spent very little on fuel filters in the past 20 years and other than having injectors changed under warranty on an 03 Duramax I cant think of a single injection system component failure. When you've only got one truck to worry about you're not going to save much money skipping filter changes so you may as well change them. For me the math is a little different.

RE: 2017+ Powerstroke 6.7 Fuel Filter

We order 65000 liters of fuel at a time and let it settle in the tank for a day after delivery before pumping it. We seldom see a fuel filter require changing on any of our equipment.

RE: 2017+ Powerstroke 6.7 Fuel Filter

I certainly don't have any interest in ordering and stocking spare parts that I will likely never use. I might change the primary filter once in the time I own a truck but it's unlikely I'll ever change the under hood filter. When you buy the kit, it comes with both filters (You may be able to buy them individually, but I did not see that as an option when I ordered mine), so I don't know why you would not replace them together. When I bought mine they came in kits as well but I don't change fuel filters unless i feel there is some reason to. So on one truck I changed the primary when I had a problem with the fuel gelling. Changing the primary was enough to get me going again. The other truck had its primary filter changed after putting DEF into the fuel tank. I disconnected the fuel line at the under hood filter and pumped all the fuel out of the truck through the low pressure side. After emptying the tank I changed the primary filter just to be sure I had gotten all the DEF out of the system. So far I haven't come across any need to change the fuel filter on my latest truck..... it only has about 25000 miles on it.

RE: Should I get a 2020 GM 3500 DRW or a 4500?

For towing an rv I would put next to zero value on the pros you listed for the 4500. I'd get the 3500 without question.

RE: Jake vs Exhaust Brake

So what is this thing? They want us to believe it is similar to a "big rig" engine brake. It is more effective than a standard exhaust brake but it is still nothing like a jake brake. If you think of an engine as an air pump you can imagine how restricting the exhaust raises the pressure at which the volume of air is being pumped at and creates more braking. Downshifting speeds the engine up which causes the engine to pump more air which also creates more braking. The Packbake holds the exhaust valve off its seat during engine braking. So with the Pac brake the piston pushes air past the slightly opened exhaust valve causing braking on the compression stroke. The pressure on the piston would be equal to the exhaust back pressure created by the restriction at the turbo. The cylinder would refill through the slightly opened exhaust valve on the power stroke and then offer the same braking as a typical exhaust brake on the exhaust stroke. Again it is the power require to force the air past the turbo that is creating the braking. A Jake brake uses a camshaft or hydraulic pressure to pop the exhaust valve open near top dead centre on the compression stroke preventing the energy in that compressed air from pushing down on the piston during the power stroke. The pressure on the top of the piston during the compression stroke is used to accomplish the engine braking and is much higher than the 60 psi or so that a PacBrake or typical exhaust brake utilize for braking.

RE: Jake vs Exhaust Brake

Would take a heck of a lot of modding to stuff a engine that uses a Jake brake in a pick up. If I'm not mistaken, I think Cummins invented the Jake Brake and granted it's use for all semi engines but some mfr's may offer their own version of a Jake to which (IMO) aren't as good. A true Jake requires the engine to be between 1600-2000 to get the best retarding power. Exhaust brakes offered by Ford, GM & Ram are better than nothing and from what I gather, folks seem to be quite happy w/ them. Not so, PacBrake makes an engine brake for the Cummins 6.7 that is a bolt on kit. Looks like it raises the valve cover about 1-1/2”. The PacBrake exhaust brake is not a compression release brake such as a "Jake Brake". It is a little more effective than a standard exhaust brake but both the PacBrake and a standard exhaust brake utilize the turbo vanes to create back pressure in the exhaust system to provide the engine braking. The engine brakes on the bigger diesels are far more effective. A pick up truck doesn't really have need for the level of braking provided by a "Jake".

Clessie Cummins, one of the founders of what became Cummins engine is credited with the invention of the jake brake in the late 50's. It was granted a patent in the early 60's. I think by that time he was not associated with Cummins and when he went looking for someone to market it, Jacobs mfg was the only taker, which, relates to how it got it's name, Jake brake. Jacobs started mfg it in about 1961 IIRC. BTW it's the same Jacobs that makes 3 jaw drill chucks. It's hard to believe something more efficient such as electric motors and batteries haven't replaced it yet.

RE: Jake vs Exhaust Brake

The exhaust brakes used on pick up trucks are all utilizing back pressure in the exhaust system. They create a little more reverse horsepower than what downshifting alone does. This little bit of added reverse horsepower is enough to make a huge difference on grade braking in an application when you are only holding back about 25000 lbs (combined weight of truck and trailer) on a typical highway grade. So for your application a simple exhaust brake consisting of a programer that controls the vanes on your turbo is all that is required. There is an exhaust brake made for the Ram that holds the exhaust valve off its seat during the compression stroke which is more effective than a standard exhaust brake but it is not the same as an engine decompression brake ... which is what has been traditionally referred to as a "Jake Brake".

RE: Saw my first 2020 GMC HD camping this weekend

I saw a Chey High Country on the highway a couple days ago. I couldn't get ahead of it to get a good look at the grill but I thought it looked very nice from every angle I saw it from.

RE: Old truck vs new truck

Fixing and running your 05 will definitely be less expensive than buying something newer. I'd buy a new diesel.

RE: 2020 GMC

Visually I see 2 maybe 3" MAX in the video. They did state that GM used the position of the axle on the springs and the shackles as their reasoning for the change.. Which goes along with my theory... Makes no difference though. We already KNOW what the result is due to the CAT scale tickets. 100#, so do some backward computations until you arrive at a method that matches the result. That will be the correct method. As an aside, banter on GM forums is that this move was only for the SB/CC models. It kind of makes sense, as that configuration could benefit from such a change. I have no idea where their mistake is but if the cat scale is right and the 2" is right then maybe they filled the truck with fuel after getting an empty weight and before getting their gross weight. How about how many passengers were aboard the truck during the weighing. A mistake I have made with the wife. When I weighed with trailer had her get out to check placement on the scale pads. As a result the front axle lost some weight. I will never say how much though. Putting 3000 lbs on a ball two inches behind the rear axle will remove 38 lbs from the front axle not 100 lbs; So the discrepancy is 62 lbs. If Andrew weighs 247 lbs and was sitting in the front seat (93 inches in front of the rear axle) when the truck was weighed empty and in the back seat (53 inches from the rear axle) when the truck was weighed loaded they would get the results they published.

RE: 2020 GMC

The video had a cutaway frame showing this. It looked to me to be pretty close to 2". Definantly NOT 5" It could very well be that the hitch is only mounted 2 inches behind the rear axle..... in which case 3000 lbs placed on the hitch would take 38 lbs off the front axle. (On a CC short box) As I mentioned on the other thread I will bet the centerline of ball is MORE than 2". That would make 100#. What is the distance in inches from axle to axle? The wheelbase of the cc short box is 158.9 inches. For a 3000 lb pin to take 100 lbs off the front axle the ball would need to be 5.3" behind the rear axle.

RE: 2020 GMC

The fulcrum is where the tire meets the road. It makes no difference where the springs bolt to the frame. If the axle moves relative to the hitch while it is loaded then the distance from the pin to axle as well as the wheel base will change slightly. So to be 100% accurate the measurements would be taken with the load on the pin. Loading the truck isn't going to change these dimensions a whole lot. For instance I'm certain the axle is not going to move forward relative to the frame three and a half inches when the springs are loaded, which is what would be necessary for the load to lift 100 lbs off the front axle.

RE: 2020 GMC

Gooseneck hitch behind rear axle centerline. How stupid. Yeah it must be waaaay back there to only be rated to tow 35k! Lofl. Some people would bitsch and complain if you hit em upside the head with a bag of money.... Industry standard has been in front of axle for ever. Dumb to unload front axle. The effect of loading/unloading the front axle varies with how far you are from the axle. We are talking 3 or 4 inches here vs maybe 50 or more with a bumper pull and most new trucks are rated to carry some astonishing weights on the bumper. You probably won't notice the small change here. However, with the trend towards short bed pickups smacking the back of the cab has become a real issue. A few inches backwards will make a huge difference on that. I hope that doesn't sound too much like a certain politician.I think the video said it was 2" The video did say two inches behind the center of the rear axle. It also said 3000 lbs of pin weight unloaded 100 lbs off the front axle. That doesn't add up. If 3000lbs of pin weight lightened the front axle by 100 lbs the pin would have to be positioned 5.3 inches behind the rear axle on a short box crew cab and even further back on a long box crew cab.

RE: 2020 GMC

I like the idea of moving the fifth wheel plate back a bit. The new GM short box might turn close to 90 degrees without popping out the back window and I dont think unloading 100 lbs off the front axle is going to be noticed.
