I just got a 2002 GMC Sierra 2500HD Duramax 6.6 L. 4WD. I have been driving a gasoline 8.1L Silverado of same year and size, but 2wd. I know nothing about diesel trucks and want to be sure to take care of it as best i can. Would appreciate any recommendations regarding starting procedures, driving a diesel vs. gasoline, what to be prepared for come winter, ANY suggestions that you may have to help me take the best care of and get the most out of this replacement truck would be greatly appreciated!

After many many hours of forum reading and trying to find a answer for a problem like mine I've finally given up and decided to just ask.
I've got a 2001 Silverado 1500 LS 2wd with the 5.3L. We were driving down a back road the other day and to simply say that it was muddy would be a huge understatement. Had I not know better I wouldn't have believed it was an actual road and not a trail. The mud was so deep that it reached clay in spots and we basically snowplowed mud with the front bumper. After making it back to the highway we went to go accelerate only to be bounced around wildly and were unable to go much faster than 80km/h due to a random and sudden lack of 3rd gear and overdrive. Limped the truck home and did a transmission fluid and filter change the next day. Fluid was filthier than heck, dark dark brown in color sort of like Cola. After that now the truck sometimes finds 3rd but 4th is nowhere to be found and once you get over about 70km/h it shakes so hard it feels like the worst washboard despite doing our best to get all the mud out of the wheels. Reverse still works fine. Looked under the truck and there does appear to be a bent crossmember but the frame still looks fine and straight.
Some backstory; Never had any transmission problems before this or signs of slipping. The tires on the truck are oversized, from a stock 245/75r16 to running 275/70r17. At present there are no rear brakes, had a bolt on the caliper come off one day and long story short ended up disconnecting them and pinching off the lines for the back brakes. We also have kids who like to play driving and occasionally jerk on the shifter, one day our toddler somehow manged to get the truck out of drive without hitting the brake and it started rolling, it didn't go very far before I stopped it but nevertheless was certainly surprising.
So my question is; what could be causing this to happen? Is the transmission completely gone and if so why no warning signs? Could it be the 3/4 clutch pack, the shift cable, transmission mounts or something else? Any input would be appreciated!

I just recently got some additional lights to put on my offroad bumper, and don't know where exactly to put the switch or how to integrate it into my dash. I just need to be able to add two sitches. I was thinking of trying to put them near the parking brake, or on the instrument panel. The instrument panel already has two spots not being used but they don't press down. Any tips or ideas would be greatly appreciated.
Extang Encore Hard Tri-Fold Tonneau cover for 2019 -2020 GMC Sierra or Chevy Silverado with 6.5' bed. In good shape. Needs new front lock because it is keyed for my truck.
Located in Thousand Oaks, CA.
I have looked and looked for more clear instructions on how to program a second key fob for my 2020 Silverado (dealership lost 2nd set). I live 8 hours from where I bought the truck and the dealership I bought it from would need the truck to program it. I am trying to do it myself. I have followed this guide but still no luck. The youtube video that is out for it is if you are programming a key fob without already having one programmed. It wasn't much help for me. Any GM Mechanics have a quick write up they can copy and paste would be appreciated.
These are the two things that haven't been enough help for me.
Thanks in advance
