Hey everyone I'm new here so try not to be too hard on me.

I have an 03 Sierra 2500. 6.0 gas 145000 I love the truck, had a 99 before this. Body is perfect no rust, interior is super clean with no issues. Tubular cognito control arms and leveling kit. Basically I have a hard time pulling my boat with this setup. I can do it but it's a struggle. I couldn't justify a diesel when I bought this but now I pretty much know that I need one. Anyway, I would love to buy a wrecked truck or motor/trans combo and do the swap. I know I have to do a body lift to clear the trans as my truck is not an hd. But I see a lot on here about issues with the type of communication the different years use. I'm a handy guy, a machinist and spent years rebuilding heavy equipment. Not worried about any of the mechanical work. But how much wiring will I have to change? Etc. couldn't find a thread with someone doing this swap on here. Thanks in advance!

Honestly, sell your truck and buy the right one. You're going to spend way more money and time converting your current truck then it's worth. You Could pick up a used DMax similar to what you have now for 10k-15k depending on what you want.

X3, unless you have some special love affair with it sell it and buy the right truck. A swap is going to cost you alot more than trading up will.
