Step 1 (Custom Trailer):
- 59" x 95" trailer base
- 2x2", 1/8" wall thickness tubing
- 205-75-15 Tires (This seems to be a common size according to etrailer)
- #9 Dexter Torflex Axle @ 1500lbs (if I can find this..)
Question 1: Do I need any cross members to support the floor in the center?
Step 2 (Floor Sandwich consisting of):
- Floor: 59.25 x 95.5" x 1/4" marine plywood cut from a 5x10" sh
- 1x4" exterior blocking
- 1x2" interior blocking
- 3/4" insulation
- Some sort of 1/4" plywood on top
Question 2: What should the bottom be coated in? I've seen roughly 100 different answers from tar, to paint, to fiberglass. I'm trying to stay away from fiberglass
Step 3 (Wall sandwich):
- Exterior: 1/8" baltic birch
- Skeleton: 3/4" ACX Plywood with 3/4" insulation
- Interior: 1/8" baltic birch ply
The skeletonization is not shown yet since I haven't figured out what the galley or interior cabinet work will look like.
Step 4 (Ceiling):
- Interior (not shown) 1/8" baltic birch ply
- Skeleton: 1 x 2 poplar w/ 1 1/2" insulation
- Exterior: 1/8" baltic birch ply
Step 5: Rear hatch:
Question 3: I am not sure what to do here. I want a 4.5-5 wide by 2.5-3 top open door. Any suggestions on what people have done in the past? I've browsed an awful lot of posts, but details have been light regarding the hinges and seals that people have used.
Step 6 (Skin): Not shown
But - planning on painted aluminum sheeting. 0.040" on all sides.
