German - this forum gets several of these posts a year and the content closely resembles your posting. The take-away is do not believe the dealer when he says "Oh yeah, the SUV will tow this." He has no reason to do anything other than get the rig off his lot and the commission check into his pocket.
Head over to the travel trailer forum. Spend some time looking at the rigs in peoples' signatures and see what others are using to tow a trailer similar in size and weight to the one you're looking at. Then, see what other people are towing with an SUV similar to yours. Please, do your homework. This is a big decision. We've seen several posts here where someone bought a trailer and had to go out and buy a tow vehicle.
