The empty trailer weighs in the area of 3300 lbs, after "decorating" about 4,000 lbs. All loaded up with motorcycles, gear, etc. about 5200 lbs. The single axle is rated at 6,800 lbs, the springs about 8,000 lbs. It has a set of HD shocks installed. Main chassis is built from 4"x3" rectangular tubing (all chassis components are steel), about 1/8" wall. Minor cross bars are 1.5 x 1.5" x 12 guage square tube. Upper trailer is built from a frame work of 1.5x1.5" x 14 guage tube and 1 x 1" x 16ga tube, skinned with prepainted .045 (approx) aluminum (from a sign company, blue on the outside, white on the inside). Trim is aluminum angle 1/8" thick, all fasteners are stainless. Floor is ( I think ) 3/4" plywood, roof is 1/2" plywood covered in one piece rubber RV roofing. The rear section of the roof is reinforced to support spectators. Windows are either from RV salvage or the bargain bin.
The rear door hinges at the top and opens by air spring assist. The suspension "carriage" is separate from the chassis and slides on large dimension angle iron for a total of about 18" of adjustment in 3-4" increments to adjust hitch weight. Brakes are electric/drum.
Sleeping quarters are in the area that extends over the truck bed, you can see the access hatch for the window AC unit on the lower front of the trailer. It has a propane stove top, small sink, microwave, about a 10 gal water tank (no hot water), small fridge, no toilet, small two person bench that is convertible into a dining area. Just the basic necessities for a three or four day excursion in a location with minimal facilities. Typical electrical system that can be powered by "shore" power, battery, or battery/truck, or generator. Only about 800 watts of AC is available on battery power.
It has a wall and a accordion door that separate the rear section from the "living" quarters.
I don't have any decent pictures of the interior....and right now it's full of stuff as it doubles and winter storage space for motorcycles and gear. But here's some pics of it during the initial stages of construction. I had to build a temporary extension of about 6' out the shop door to accommodate it during the winter months while I was building it. Took about 5 months to build with the wife helping....and she is a good shop helper, can do most everything but the welding.
