We are towing a 28bhbe elite (all options put us around 7200# delivered) with an Expedition that can tow 9200#. With 4 kids and stuff, we feel like we are at capacity.
That aside, my sister and dear brother in law bought a TV with a capacity of 6000# (but in Europe is rated for 7500# - he is an idiot) and a TT that was dry weight of 5790# convinced they could tow it. They went on a long vacation around the country and the hitch actually broke twice, dropping their trailer in the middle of no where both times (makes for an expensive tow truck bill!). We tried to tell him it was the tongue weight the first time and he was adamant he was fine and refused to listen to us and instead blamed the invisi-hitch dealer. After the 2nd time, he is now having to trade in a damaged trailer for something smaller after only owning it for 6 months. Plus I am sure he damaged the uni-body frame of his brand new TV he bought to tow the brand new TT. On the bright side, he didn't kill (or even hurt) anyone. I had been scared all summer!
