Well here is ours
Its an 07 Starcraft 21rbh XP. Its 21feet from hitch to bumper. Dry weight is 3000lbs. Its an expandable trailer so we cut down the weight. Has a queen bed, double bed, 2 bunks and also a table that can fold down to a bed as well. 6-8 people can sleep in it.
Our Pathfinder tows it no problem, has lots of power for it. Downfalls are that the pathfinder sags in the rear. We have just installed the AirLift rear bags to get rid of the sag. The other problem is the mirrors. They don't stick out far enough to see around the trailer. I am looking for the stock titan/armada mirror to install to compensate for that.
All in all, the Pathfinder tows our 21ft trailer just fine.
