Ok so my Xterra is automatic which has 5000lbs towing and I'm pretty sure the tow hitch is 500lbs.
After reading through the responses these are the things to consider:
Length of trailer to length of Xterra.
Gross weight
Dry weight
Tongue weight for hitch, cargo weight of Xterra. Don't understand how cargo weight effects what you can tow.
Weight distribution hitch/ electric brakes, not sure where these brakes are.
Tire rating
Anything else.
I am planning to go to the RV show in Hershey Pa in Sept. If I don't make that one then the Edison NJ show in January.
I am in know hurry, I want to do this right the first time.
Thanks for all your help .
