Looking at a Ram 2500 to pull a 7K travel trailer. It will be a gasser with the 6.4 hemi. Should I get the 4.10 rear end or will the 3.73 do what I need?

3.73 is fine unless your pulling a LOT in the mountains. Then I would only consider 4.10 is you like to run really fast.

It depends, if mostly for towing, the 4.10 is best choice. The 3.73 will work for that size trailer, and maybe get slightly better mileage, in every day non towing. If you decide to get a bigger trailer at some point, you may wish you'd have gotten 4.10.

With today’s transmissions, the 3.73 is fine. I’m happy at 3.43 and 5200 pounds of TT.

I had one. Go for the 4.10s. The gap between 1st and 2nd is big and the 4.10s dull that a bit. Also, the GCWR and max tow rating increase 3000# when you go to 4.10 from the 3.73.

The 3.73s will easily tow your 7000# load, but the 4.10s will allow for a bigger load if you upgrade RVs.

Does RAM offer some sort of locker or limited slip in the rear axle?

My last pickup had 4.10s and the one I have now has 3.73s, and I have seriously considered doing a gear swap to 4.10s.
My mileage is worse with this newer pickup, but they are different.
