Mine is about 5X9 1/2 and a bit taller than normal. I have fiberglassed/epoxied 3/4" plywood sides, 3/4" framing skinned with 1/8" ply on the inside (insulation throughout), and two 1/8" layers of ply on the roof, also epoxied. I just had it weighed yesterday, and it came out to 1280 lbs. The cabinet face frames and the water tank, etc... are not in yet, so I am guessing that when all that is in it will be closer to 1350 lbs. It's a bit on the heavy side, but my Outback pulls it with no problems.
