At this point I could fit up the hatch lid. I made sure all the angles and arcs were proper. The exterior surfaces were preped for the aluminum. The aluminum is from the roof of a tractor trailer and was procured from a truck auto body shop. ($300 the most expensive part of the teardrop)
The teardrop walls were sanded and all screws were counter sunk. The exterior was covered with an industrial contact adhesive to keep it in place while the holes for doors and lights were cut. Holes were cut and or drilled and finished with a flush router bit.
The sides were secured down, this was the easy part now for wrapping the roof. I wanted to do this in one piece (less chance of leaks) I secures the front down with screws and adhesive. then I used cargo straps to get a tight fit around the whole roof. This was a tough job to get it to fit properly. Then the holes for the vent, galley hatch, and tail lights. The tail lights took the longest to do as these were precision cuts and had to be right the first time.
