Teardrops n Tiny Travel Trailers

I was glued and screwed a one-piece 3/8" plywood countertop onto its frame in the galley. The 5200-BTU air conditioner was test-fitted in the middle below the countertop. It was so tight I had to take the case off the A/C unit. Put a grommet in the drip pan, flared a piece of 3/16" copper tubing, drilled a hole through the trailer floor and installed another grommet, and put the copper tubing through the floor to drain A/C condensation.
