So, I imported a picture of the side profile into Sketchup, and tried to take some measurements (set a baseline of 15" at the wheel diameter, and scaled from that). If I'm close at all, it's a pretty compact rig. Looks about 7.5' stem to stern, The frame appears to be 4 x 6. The doors I can't measure well, but are roughly 3' tall. Inside height when open is somewhere near 5'. Closed, the body is about 4' from highest point to lowest (which is at what appears to be a storage box in front of the axle).
The lid looks torsionally stiff, the bottom somewhat less so. However, the bottom walls are relatively short, and look to be attached to the floor in a way that would limit flexing.
Opening the critter on-site might take some flexing of the owner - I'm guessing you have to hold the lid open while you reach in to grab the door frame and fold it up. I see gas struts inside, which should be of assistance.
The roof rack is really cool, like from a vintage VW, custom made, no doubt. The awning looks to be supported by flagpoles from the hardware store. The wheels make it look like it's going fast even while sitting still, and are a major part of it's cool factor - Cragars? I'm wondering how the hinge on the front stays dry when towing through a monsoon at 90 miles an hour...
How am I doing?
I love this trailer. I want to buy it dinner, maybe a movie and a few drinks, and see where things go...
Cheers,
