Look at forest river. I had a 625D with huge slideout dinette, and pottie/shower. Downside of the those two attributes: Zero inside storage. WE bought it new in 2010, used it two years, traded it. Dealer sat on a year, and someone bought it local. I watched for a year and never saw it used. Its for sale this season. It took 2 hrs to fully setup campers like that. You have dual drains, no gray tanks, and have to mess with creating the wheel each weekend. Truck carries everything, and that adds to setup and break down. If I did it again. It would be a nonslide zero utility pup, but that will never happen.
