Towing 5200lbs with a 06 Nissan Pathfinder

Have you looked at Ameri-lite trailers? I'm not sure how far they will get you below the 3000 lb dry / 5000 lb wet weight but they have several 7 ft wide trailers that will lower wind drag. Aero-lite had some 7 ft wide trailers but I don't know if they still do. To drop 5-800 lbs to get comfortably inside your tow ratings will usually require a trailer with a dinette/bed combo rather than a permanent bed. Hybrids and tent trailers will offer some options but they still don't have permanent beds. If you are not looking directly at the physical trailer but at a brochure or on line be-careful on what they are including it the listed weight. Refrigerator size, oven, A/c etc. all affect weight. We looked at a trailer that was listed at 1700 lbs. But it turned out that was with no cook top (it had a 1 burner hot plate), no propane hook up at all, no sink or water tanks, a electric space heater and a compact 110v dorm fridge. So as we added the necessary items to make it a use-able camper it jumped to almost 2200 lbs. I know that was an extreme case but it was a lesson learned to read the fine print and not just look at the picture.
