[posting some trip reports on that forum, titled Strange Tales Along the Road]
My 7 x 10 + 3' V-nose was ordered from the factory with 3 windows, including an RV style door, barn rear doors and insulated walls and roof for under $5000.
Bed frame is a $40 Walmart shelving unit that accommodates 4 large plastic totes for storage. 3 cabinets for storage are only held in place by plywood counter top fixed with a few dabs of Liquid Nails.
Cut a hole for a simple sink which drains into a removable bucket.
Im in the process of installing a sink faucet powered by a Whale MK 3 foot pump.
This photo was taken in Death Valley, Mesquite Springs. Shows my camping setup when I have the Parawing deployed.
Other newer photos in my album show how the CT looks now with the bed across the rear. Gives me much more room and an open feel. Also shows the cabinets I installed. In one you can see my simple sink drain to a 'gray water' removable bucket.
Removed the carpet and replaced it with interlocking 2' x 2' rubber tiles designed for use as a workout pad. My window coverings are plastic yard signs encased in Reflectx aluminized bubble wrap and velcroed at the corners.
