I got a heck of a deal on a new 2018 Ram 3500 DRW diesel but I was worried because it came with a 68RFE trans and 3.42 gears. I tow a 5th wheel that weighs 13500lbs loaded but luckily it had a puck system and the dealership agreed to let me take it home for the night. I put my hitch in the truck and took it for a test through the mountains towing the camper and it did great! I never try to tow over 65 mph anyway so when really hilly I just lock out 6th gear and roll on. Plus my fuel mileage pulling is around 12 to 13 and empty around 22. So I have no regrets at all!!!! You can see my setup on my profile page.
Nice, I wouldn't worry too much, not a newer Ram, but currently towing a 5er at 12,700# 20,500# combined. The Ram is slightly juiced DS Power Puck, and RV275 injectors I figure about 300 hp and 600ish # torque. This is with a 5 speed manual and 3.55's.
So with the HP and Torque of new Rams I don't see an issue.
