Having receintly bought a TT and being a newbie to bigger trailer towing I can attest that you better know what your TV is good for before you fall in love with a TT. I visited around six TT dealers in my search and everyone of them said with my Yukon I could choose just about anything on the lot. We ended up with a TT that is 5500gvwr because I had some, not all, the knowledge to make a wiser choice thanks to this fourm.
Now anyone I speak to who wants to get into TT camping gets my directions to this site. Knowledge is power, and the advice you get here isn't being swayed by next months comission cheque.
