  1. My plan has been to change oil/filter every 5k, and maybe use this stuff every 10k. I'm coming up on 10k miles so I'm curious if anyone has used this intake cleaner, or one like it, on a 6.6. Seems pretty simple/straightforward to apply, using the PCV line, and reviews and independent you-tube videos would indicate it does something beneficial. Anyone tried it? CRC GDI Cleaner
  2. I saw that episode before I bought. I don't put much stock in it. While I understand why they run that test the way they do, to remove driver variability (put it in tow mode, put your foot to the floor, steer), no one would actually do that in reality. They uncovered a programming flaw with the transmission that for some reason wouldn't down shift when needed. It bogged down to something like 25 mph before it downshifted. Not good, but not representative of what any actual driver would do. If I ever needed to tow up that hill at max rating, I'd lock out the top 2 gears... or a
  3. Like many, before I owned one I thought the multi-pro was a gimmick. I use it all the time and with a truck this tall I would not want one without it. Just like 99NCAA, I drop the inner gate about 100% of time to get closer to the bed, or to quickly drop the step to get in/out. I'm not one to leave a hitch installed when not in use, so that issue is not an issue for me at least.
  4. I can't imagine the 5th wheel/gooseneck package would affect ride quality. It's essentially a plate welded to the frame rails. There must be something else going on with tires, tire pressure, or...?
  5. Are there any admins monitoring the site? I've been seeing all the same issues. Even worse on my phone browser where any link leads to the same page in a thread.
  6. That is a cool idea. Did you find a good weatherproof switch as well? Rozz, I like the idea of a diode as well... just in case.
  7. Large pair of channel-locks works pretty good too.
  8. I'm not enough of an automotive electronics experts to know if this would cause unintended problems... To add a switch in the bed to turn on just an in-bed light, what if: You teed into the 12v+ off the 7-pin trailer connector (always hot), and ran that 12v+ feed to a toggle switch mounted somewhere handy in the bed (like near the old man handle on my GMC), then ran the output of the switch into a tee connector with the existing positive feed going to the existing bed light (there by the old man handle). So you flip the toggle switch and basi
  9. Here's my write up on my initial tow with the 6.6 gas. I think you'll find this truck/engine just right for what you are describing... www.gm-trucks.com/forums/topic/248308-towed-the-boat-for-the-first-time
  10. You're right in that the diesel will always out pull the large gas engine offerings. You are also right in that you aren't buying a gas 3/4 ton truck for the 50 extra HP/TQ numbers. For people on the fence, you go with a 3/4 ton for the "everything is bigger/more stable". The 6.6 is cast iron block, forged crank, more cooling capacity, more oiling capacity, etc than the 6.2. It's made not for speed but for longevity running at/near its peak power output at 4k rpm. The suspension, frame, brakes, axles, curb weight are substantially "more" than a 1/2 ton of any flavor. While th
  11. As I once said in another thread on here somewhere, the GM and the Ford gas 3/4 tons have "essentially" the same towing, payload, mileage, and engine performance numbers. Would a 10 speed improve the GM's? Probably. Is the 6 speed a reason to not consider it since the Ford has a 10 speed? Not that I can ever see/understand. The GM 6 speed is one of the most reliable transmissions GM ever made (and for the new HD application they added clutch packs and an improved TC). The new Ford 10 speed is now seeing a "recall-not-really-a-recall" for a substantial number of 2020 MY trucks.
  12. I bought the same thing (from Lowes). It is a perfect fit. And yes, there is usually dirt, dust (or rain water) on it when I pull it off to fill up. I just set it to the side of the fill neck while pumping... or sometimes use it to hold open the filler handle at a station that cut the little handle latches off.
  13. In my experience, with the gas engine, you have to be in tow/haul mode for "grade braking" to come on. When in tow/haul, I've noticed the truck will apply engine braking even on level ground, whether loaded or not.
