We have a 2014 Ram 2500 4x4 with the 6.4 motor and 4:10 gears, with a Camplite 6.8 in bed, generally towing a Can Am Commander or Sea Doo. The good - great motor/trans combo, good ride (unladen) although not as good as our 2010 Ram 1500 which was like a caddy. So, camper-wise, while the payload numbers are there, my theory is the springs are quite a bit further inboard (compared to the leafs) and thus the lever, that is the tall camper, contributes to a significant amount of sway (without mods). After our first trip a few months ago, I was seriously questioning whether I'd made a bad decision on the truck. I embarked on a three-phase suspension mod program to see where I could fix the sway. First a set of Bilstein shocks, a slight improvement, next a Hellwig swaybar (no big-wig for these trucks yet), a noticeable improvement, but not acceptable, finally put a set of Timbrens (the HD model) and wow what a difference. This is what the truck should have handled like when we got it (my opinion). The HD Timbrens are stiff, no doubt, but there is NO sway, and I prefer it that way. Soooo.... should I have opted for the 3500? Tough to say, I love the truck/camper combo now, so I won't second guess myself at this point. Bottom line, expect to make some suspension mods to a coil sprung Ram 2500 if one decides to put a camper in the back. Just my two cents.
