Have you taken possession of the Travel Trailer yet? If not, I would seriously consider stopping that purchase and take a minute to plan you next move.
IMO the Tahoe isn't going to do well pulling that trailer. If you buy the trailer in short order you will be buying a new tow vehicle. I did, many others have done it, and you are about to do it too. I tried to pull a 29' dry weight 5300, ready to camp weight 5900, with a Tahoe. It never stranded me but it wasn't fun...after 1 summer I bought a Duramax.
If you don't mind a new tow vehicle keep on this path, if you absolutely don't want to have to buy a new tow vehicle --- fund a smaller/lighter trailer.
