Towing Newbie

Are you buying new or used? I don't know much about the newer Pathfinders but I think they are a crossover design these days. The previous ladder frame version with the 4.0 V6 would work well for that trailer, as would a 4Runner. A midsize truck would also work. You won't win any races going uphill but you should be able to maintain adequate speeds in most cases.

I would be sure to invest in a good hitch with sway control as your trailer is going to be more prone to sway with just one axle.
