Anyone run a Ram 3500 with 6.4 Hemi?
Looking into a 13,500 lb gvw fifth wheel. It weighs too much for my F250. Does anyone pull anything that heavy with a 6.4? If so, how do you like it? Does it handle the mountains?

No opposed to a diesel, I have a 2012 f250 psd now. I was just contemplating a big fifth wheel vs large tt and didn't want to shell out 10k + for a diesel if the 6.4 could do the trick. I could sell my truck and buy a new 6.4 for about the same money.
Real world a cummins is about $6k more than a 6.4, if that. And you get at least be that back on resale, not to mention better mileage. I only drove a 6.4 unloaded and it was nice, but it isn't a cummins. At that weight is think hard about a diesel. Just my 2 cents.
X2. Especially if you live around any hills OP! There are a few 6.4L owners here that are a little overly optimistic on what they say that engine can do.
Although to be honest I don't think it is the 6.4L and has more to do with the transmission. The gear ratios in that 66RFE are fine for a diesel since it was modeled after the 68RFE, but Ram should have made each gear a lot shorter for the 66RFE mated to the 6.4L. If you look at the competitors trucks like the Ford 6.2L with the 6R140 and the 6L90 on the GM with a 6.0L, they actually put more torque to the ground in almost every gear due to the torque multiplication of the transmission.
