Why aren't travel trailers made this way ?
People have complained about the build quality of TT for years. The biggest disaster is a water leak. These typically occur at the roof seam or around a window. Once the water get inside the wall it migrate down to the floor and in a couple of years the floor is rotten and you have a VERY EXPENSIVE repair on your hands !
Now look at the picture of the cargo trailer.
Notice the nice, smooth transition from the roof to the side wall. Sure there is a seam on the vertical surface, but water would run right over that.
How about the horizontal roof top ? How is it seamed to that edge piece ?
That is a continuous 1 piece aluminum extrusion. The joint at the roof (top right) is part of a half lap joint. The roof metal would be formed just the opposite so the 2 would hook together. This is very common joint in HVAC duct work. If pressed together it is a very long lasting LEAK PROOF joint !
Notice the little protrusion on the lower left side ? This "kick out" rain water so it does not run/drip down the side !
WHY CAN'T THEY MAKE TT LIKE THIS !
