Ford Expedition 2012 EL Limited 31 foot Trailer

Well, I have been feeling I might be pushing it. Looking to see if I can pull another 1000# out of the TT looking at diff models. Problem is, finding something with good height in TT. I am tall, allot of TT's have low ceiling, the Cougars have decent height in it.

Looking for something with queen / bunks in separate rooms, good ceiling height, I suppose around 6200#.

Any idea's on models/ mfg that make TT's with good interior height at abour 28-30' long?
