Is this a regular issue with Eggs assembled this way like Uhauls as well so this needs to be inspected upon purchase? How would you even check for something like that as the carpet covering the seam may hide it. Is it really something to be concerned about?
I have a 1980 Burro
that I am restoring. The seam on mine was cracked where it meets the floor in both the front and the rear about 8 to 10 inches long. The cracks may have occurred because the floor was rotted and sagged. During construction, when they glued the right and left half together they just used thickened resin. They did not use fiberglass cloth, mat or tape, so there is no reinforcement across the seam and resin alone is brittle without reinforcement. It is possible for the seam to have cracked in the roof causing the leak, although a leak around the roof vent would be more likely and could be misinterpreted to be a seam leak.
I would suggest checking the floor for rot very carefully. When my Burro was built, they did not seal the plywood edges of the floor at the wheel wells very well and water gets into the plywood and can not evaporate because of the fiberglass on both sides of the plywood.
