Yesterday, my wife and I were talking about her son wanting his Old Travel Supreme 5th wheel moved for Eastern Washington to Marysville in Western Washington. She said how come I said I could not move it up from Oregon a few years ago with Old Blue our 2001.5 RAM, and am now saying that the newer 2015 RAM can move it now.
So I had to explain that the new truck is a completely different animal vs the old one.
We towed a 12,400 lb 5th wheel with Old Blue and it did quite well with over 6K on the rear axle a lot. Like Russ it came with tires rated to 3415 each vs 3042. It was a good rig, however it was not in the league of the newer SRW 3500's.
People will say the RAM 2500 is just as capable, and to that I say, RAM does not think so. If buying new get a 3500.
