Also proves that tonneau covers are good for mileage. Most people assume that putting a tonneau cover on is equivalent to driving with the tailgate open. This proves that's not true. Driving with the tailgate open results in a completely different airflow than driving with a tonneau cover.

I never could figure out why people drove with there tailgate down, even if they did think they were getting better mileage (which they were not), cause the paint on it gets chipped to sh*t.

I would never drive with my gate down anyways, not only would it look a little odd, but hit a bad bump & the gate pops out of joint your f****d out of a gate and gotta spend a couple hundred on a new one. just doesn't seem worth it to be for a very small mileage increase.

That article is fine and dandy, but I get all my scientific evidence from Myth Busters! No but really nice article! I have never driven with down for the mileage, only because the load was to big close it!

a buddy of mine years ago would drive with it down when his wife drove only because she was uncomfortable with the limited visibility behind the truck and found it better with it down, especially when backing up

Yep, the article is very detailed.

I read some years ago in Popular Mechanics (I think) that with the tailgate up, an air bubble is created in the bed which allows the air to go smoothly over the cab and the cargo box. With the tailgate down or gone, there is no air bubble.

 

I also saw a test of 2 F150's that were given a diet of one gallon of gasoline each that showed the tailgate up version and one down. The w/gate motored farther than the w/o gate.

      2026 6.6 L5P oil cooler leaking oil at 4,000 miles

      By Brendan C · Posted

      New to diesel trucks. I happened to find my oil cooler leaking oil externally with only 4,000 miles on the truck. I didn’t realize this was an issue until I started researching it. Dealer is going to replace it under warranty but I’m wondering if there’s anything GM is working on to fix this issue. I’ve heard the oil filter used is the same as they use on their V6 motors and that’s what is causing the problems. Should I switch to a bigger filter or keep using the OEM recommended?

      Seems to be Missing a lot of Updates

      By Vu1can · Posted

      So, GMCustomerService:  Judging by the Update History pictured above, is this truck missing any updates that it actually needs. If it's just for the infotainment system, the radio is working fine and no trouble with SeriusXM. and Android Auto is working fine wirelessly with my phone. Some months ago, an update notice was sent to my truck. I approved the update and it finished saying that the update was successful, but it seems that whatever that update was, it didn't actually get installed - at least not if I'm to go by the Update History shown above.   So, again, are there any updates that this truck really should have? I've checked with my dealer but they're reluctant or commit to anything and if I want them to check, they require a $200.00 fee just to check it out and then I'd have to pay for the actual update(s).    Ignorance is bliss, and if none of the updates goes to fixing any mechanical discrepancies, I'll just leave things as is.

      Electrical Problem - solved

      By CNH-320 · Posted

      Hey everyone, I recently had an issue with my 07 2500HD GMT900. My DRL’s stay on at all times. Right front turn and right mirror turn signal indicator stay on solid at all times. By “at all times” I mean the only way to make them go off is disconnecting the battery. I tore the headlight assemblies out, tried disconnecting the harnesses to eliminate bad wiring at the harness, I unplugged the headlight switch, no change and the mirror turn signal still stayed on. My first thoughts were : Bad bulb and/or socket somewhere, under hood fuse panel bad, bcm bad, tail light or trailer wiring problem, or some random short to power in the harness.  Possibly a bad ground but unlikely. I had a big clue in the fuse panel, it had a burnt smell. I started pulling every fuse that had to do with DRL or right turn/park lamp. Nothing made the right directional turn off but pulling the DRL2 fuse made the DRL’s go out.  After studying wiring diagrams, I found that both problems had that fuse panel in common, the bcm also controls both problems but knowing the fuse panel had a burnt smell I removed and disassembled the fuse panel and found a little corrosion on the printed circuit board.  I ordered a new fuse panel from Amazon for like $260. When it arrived I installed it, and put everything back together, the problem was fixed. I figured the fuse panel needed to be replaced anyway so that was a logical place to start. Hopefully this story helps someone in the future. Regretfully I didn’t scan for codes before I did everything.

      That stinks. I’m sitting on the side of the road right now with the same issue. Never had an issue before taking it in for the ground strap recall. Now I’m outside of warranty and they’ll probably want $200 just to diagnose what they already “fixed”.
