What gears do I need?
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?

I have no dog in the fight of 3.73s or 4.10's with the 6.4L, but I would recommend the Tracrite helical gear limited slip that these trucks come with. It reacts quickly making it much easier to take off in slippery conditions. I have a friend who has a similar truck to mine without it and he has to do a lot of throttle manipulation in similar situations. I just hit the throttle and go. If it slips, then the Tracrite kicks in and off I go.
The Tracrite should prove superior. I have similar 2x Eaton Truetrac and they are still amazing with 125,000 miles on them.
6.4 and 7,000 pounds... the gearing will not matter much but I would not avoid 4.10 if the truck you want has it.
