Here is Doug from Oregon’s Explorer Box trailer with a M.O.A.B tent unit kit on its maiden voyage for some camping in the Nevada desert.
He built it with high ground clearance for rough off-pavement towing with his Jeep.
On his Explorer Box he used waterproof marine deck hatches as side doors instead of a front door. On his M.O.A.B he fished a ratchet strap around the bottom of the travel cover to attach it. There is a 1/2” ledge around the top of his trailer box that the strap cinched under. Because of Doug’s idea, on the new batch of travel covers, we left the bottom corners open for more attaching flexibility.
