Welcome to the Forum!
Check out DRV (formerly Doubletree)
They have a 43' 5thwheel - will customize to almost any request (limited mostly by how much you want to spend!)
You will need a BIG truck to tow it!
DRV makes a GREAT rig and as usual - you get what you pay for
The website is http://www.doubletreervsuites.com/
Check the floor plans.
