Let me start by saying I am NOT trying to start a fight. My family an I are converting to the full time RV life and are going to pull a heavy tow hauler across the country. I recently sold my 2014 Gas 350 and am looking for a solid dual rear wheel drive diesel. I'm struggling to find the most reliable truck that will get the job done and have pretty much eliminated Dodge from my wish list.
I'm looking for a used DRW 4x4 in the $35k to $45 range. I've narrowed down my search to three vehicles somewhat in my area. I'm familiar with the Ford issues, EGR, possible glow plug, etc. However I am not familiar with the reliability and common issues to look for on the GMs. Does anyone have experience or feedback on the best truck for the job that should give me the least headaches?
2014 Ford 350 Platinum 104,000 miles $43k
2011 GMC 3500 Denali 79,000 miles $37k
2016 Chevy LTZ 107,000 miles $42k
Thanks guys!
