you would be looking at around 8k combined, depending on constuction, I have an aluminum 24 footer & its placard on the side reads 8700 cvw. But I have not weighed it. My 18 foot steel trailer (open weighed 2200 lbs) If you are looking at an SUV make sure you can get it in a 2500 version, example Avalanche,tahoe,suburban,excursions ect. The problem with enclosed is not only the weight( and all your other weight for spares tools ect) is the aero! Case in point, A few years ago I towed back from a race without my car(2800 lbs) the thing towed exactly like it was a full load! even the fuel mialage was the same. That was with my gen 1 ford lightning , which would really haul the mail. The difference betwen that truck & my ne 250 is unreal. Not in acceleration, but braking, handling & saftey ther is no comparison. I think one of the big factors is the LT tires load ratings.
