The top can be parallel to the ground, that way you won't loose interior space. Notice these flat-top fenders; if they were doubled with a piano hinge on the outer edge, they could fold out into work-benches.
Why the 32x62" dimensions? Will you taper all the way to a point or truncate to a flat back? Ignore that this is a tear-drop. The edges [to scale] are 4', 3' and 5' with a 2' wide rear, based on a 4x12' plywood sheet.
The axles are pushed back to keep them within max width. The next iteration [were there one] would have the edges 4', 4' and 4' with the axle[s] in the middle section in wheelwells cut into a 5' wide floor.
Here's the frame and floor laid out over a teardrop template:
What do you propose for materials?
Plymetal Swingdoor panels are plywood skinned with aluminum
Quote:
The Nudo Ply-‐Metal Trailer Door Blank consists of a 3⁄4” 7-‐ply, Exterior Grade Plywood core with either aluminum on both sides or an aluminum exterior face and a galvanized steel inner face.
The door blank is primarily used as a replacement panel cut‐to‐size by a repair facility to fit all standard semi-‐ trailer rear openings.
The exterior aluminum skin is generally pre-‐painted white while the interior aluminum or steel skins are usually a mill finish.
The most common sizes are 49”x110-‐1/2” or 49” x 121”.
