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?

At 7K# either will probably do fine. My truck has the 6.4 Hemi and 4.10, but I tow a high profile 5er that weighs about 12,500 #. It has done a fine job in the eastern mountains (TN and KY areas) and over a 2,000 mile trip I averaged 8 mpg towing the fifth wheel. My advice, if you ever think you may want to go larger with the RV, then get the 4.10. If anything, with the 4.10 you will get a little better mileage around town and a little worse on the highway (about 1 mpg).
