RE: rv garage

Drywall in the brightest white paint I can find and lots of lights. Fire resistant and I hate working in a dark shop.

RE: Camera equipment on commercial jet...advice needed

Film (what's that?) is sensitive to X-rays, and higher speed film especially needs to be in a protective sack to avoid fogging. Memory cards are not sensitive, any more than cell phone memory (in many cases that would be some variant of an SD card, even) or laptop SSDs are. No problems with X-raying them. Vibration on a plane is not generally a problem, no different than a car or truck or RV as Fizz wrote. The only slight difficulty I've had is having the security people need to paw through the camera bag manually because all my lenses and other appurtenances looked rather strange on the X-ray machine. I was traveling with about a half dozen lenses, ranging in size from the tiny DA40 to the superb but fairly large Voigtlander SL 125/2.5 macro. You use Pentax equipment too...ie; DA 40. I'm concerned that airport personnel will try to take my lens off the camera body and break something. Never had a problem, they must see a hundred SLR's go through in a day. I doubt they would want to break your stuff anyway and if they wanted a lens removed for some reason, would ask you to do it yourself.

RE: 5th Airborne Pressure

I have trouble keeping air in mine, especially if I disconnect. I have to re-inflate almost daily when we are on the road. A bit of a nuisance but well worth the improved ride. Doesn't sound right, mine sit for a couple of months before I need to add any air.

RE: 5th Airborne Pressure

I don't check the pressure, I just inflate it to the inspection notch when hooked up.

RE: towing with older diesel trucks

I had a 2001 5.9 auto. Didn't have any problems with the transmission towing 10K. The fact it is a four speed with a big gap between 3rd and OD was what I didn't like about the auto. No second gear torque converter lockout could also drive up the transmission temperature on steep grades. If you don't mind a stick, look for a 6 spd manual. A bit more power and torque plus a higher tow rating. The 7.3 Ford uses a 4 spd auto as well. Something to consider.

RE: Jeep V-6 engine

The 4.0 I6 was developed by American Motors when it owned Jeep. Made a whole 190 HP. Not bad in it's day but nowhere near today's V6's.

RE: Jeep V-6 engine

Give the Pentastar DI and hang a turbo on it. I could see the Hemi disappearing except for some SRT and truck models.

RE: Proper tire pressure for load range E 10 ply tires

On my Dodge Ram 2500 the "Light Load" pressure is 45 lbs in the rear. Those are E rated tires and the door panels recommended pressure. The dealer is telling you what he thinks. Not what he knows. Same for my 2011, 3500 SRW. Calls for 60 in the front at all loads though.

RE: rpm when towing

Mazda Skyactive gas engines are using a 14:1 compression ratio. The are planning on going to 18:1 with gas engines. Skyactive 2

RE: rpm when towing

A point here is that DI and turbocharging has made the old adage that the gasser needs to rev like crazy to produce power no longer holds true. The 3.0 Audi gas example that was given has an extremely flat torque curve, one any diesel would be proud of. It produces that 364 lb ft from 1370 RPM all the way to 4500 RPM. BTW that 3.0 diesel in European S trim is now putting out 340 HP and 516 lb ft but we know it won't meet NA emission standards. Wish it did cause it must be a hoot.

RE: rpm when towing

All these numbers are at WOT so it is just as important to have a gear which allows you to maintain WOT without either over reving or losing speed. My Cummins 650 has a flat torque curve, it peaks at 1500 RPM and stays flat until 2900 RPM. At 1500 RPM at WOT it can make only 186 HP. At 2900 RPM it can make 350 HP. Another graphic example of what a turbo DI gas engine can do is the new Audi RS3 engine. It is a performance engine but it also comes with a four year warranty. 2.5L 5 cylinder HP 400 hp at 5850 RPM 160 hp per litre Torque 354 lb ft from 1700 to 5850 RPM That is 141 lb ft of torque per litre at 1700 RPM compared to the Cummins HO's 134 lb ft per litre at 1700 RPM.

RE: lost an entire wheel and drum

If you just pack the bearings and leave the large void in the hub greaseless, the grease in the bearing will get hot,melt and run to this void in the hub. I've never had that happen.

RE: Legs up/ Legs down?

Sure, when heading south for the winter we don't unhook for six days. I put the jacks down to stabilize (not level) the trailer but there is no need to. If you do, just do it before you put the slides out. If the spot is a pronounced up or downhill, you might have to disconnect.

RE: rpm when towing

Thats cause the Cummins is most at home at 2100rpm. Peak torque. Everyone gets caught up in the HP craze. Horsepower doesnt do crapola for pullimg grades. Gear it for peak torque and let it pull. Comments like this are what confuse people. Here is the math: If you have a 2015 Cummins/Aisin it makes 865 lb ft of peak torque at 1600 rpm. If it is run through gears to slow the rear axle down to 507 rpm (5th gear with a 4.10 rear end) the torque on the rear axle will be 1600/507 x 865 or 2768 lb ft of torque. Now rev that engine up to 2800 where it makes 385 HP and the torque drops down to 722 lb ft. Drop down to 3rd gear. Your rear axle will be turning 509 rpm. The powertrain will be able to deliver 2800/509 x 722 or 3972 lb ft of torque to the rear axle. So in 5th it can put 2768 lb ft to the rear axle and in 3rd 3972 lb ft to the rear axle. HP is king ...... if you have HP, torque can be generated with gears. These numbers assume no power loss through the gears and so are to demonstrate the physics rather than be absolute values. Yep, that is why high HP gas engines, can't tow what a diesel. More energy per gallon. I will take a Low HP/High torque over a High HP/low torque gasser any day. Diesels don't need to spin fast to move a load. Maybe not but it moves it a lot slower. Boosted gas engines put out peak torque at some pretty low RPM's as well. I have one that hits peak torque at just over 1500 RPM.

RE: rpm when towing

Next time I am going to try that. 3300 seems awful high. There is nothing really wrong with what your doing it just means that you will go slower up the hill. Anyway the way to maximize your speed up a long hill is to start by anticipating the hill. By that I mean downshift before the truck begins to slow down. So if you are going 60 mph in high gear with 3.73 gears your engine will be turning about 1713 rpm. Drop two gears and you should be travelling 60 mph and revving 3117 rpm. If the truck is pulling a long steep hill it can slow all the way down to 42 mph before you can shift again. At 42 mph your engine will be revving 2183 before the shift and 3500 after the shift. Well don't know the listed red line on the Cornbinder 6.0. but 3,300 rpm would be 100 rpm over my CTD 5.9's red line. I don't like taking it much above 2,500 as that seems to be the point power flattens out. Thats cause the Cummins is most at home at 2100rpm. Peak torque. Everyone gets caught up in the HP craze. Horsepower doesnt do crapola for pullimg grades. Gear it for peak torque and let it pull. Wrong

RE: lost an entire wheel and drum

Allways seemed like a huge waste of grease to me, filling a whole hub with grease to do a job that only requires a few onces. I'm still using the same tub of Penzoil 707L that I bought in 2002.

RE: lost an entire wheel and drum

Do cars and light trucks even have packable bearings anymore? I do my 5th wheel every two years.

RE: rpm when towing

My early 11 Cummins 650 and 3.73's works different. The RPM will also be different than you guys with 3.43's. It will hold on to a gear too long before it shifts down. It will go from 6th to 4th with a great roar if I just leave it alone. If I pre-emt it by shifting to 5th with the ERS, it is much smoother and 5th is often all I need for smaller hills. I just shift it to 5th then put the ERS back into 6th so it can shift back up when it is ready. On steeper hills I will find the gear that works and leave the ERS in that position so it doesn't hunt.

RE: lost an entire wheel and drum

I've always hand packed my bearings and have never had a bearing problem. Touch wood. Except of course for Lippert axles which come from the factory with grease leaking all over the brakes.

RE: Is 70 the age to stop towing

I was almost 70 a year and a half ago when I took the driving test required to tow a trailer over 4600 KG in this province, so I don't think I'll quit quite yet.
