Because, I believe, your frame side members are angles with a leg pointing up, it does raise the problem of creating a water trap that can encourage the wood/plywood to rot quickly. To get round this, there are two things in this cross-section to consider:

- The red pieces are 1/8-1/4"packers, preferably of some inert material like plastic, that support the body clear of the frame except around the holding-down bolts. This aims to allow any water running down the gap to drain away.
- The orange piece is a deflector that aims to send any water that's running down the sides outside the frame, rather than into the body-to-frame gap.
Both of these are probably excessive if the trailer will always be stored indoors, but I would fit the red packers even so.
Trying to fill the frame-to-body gap with some filler like silicone is, I think, destined to fail in the long run and, when water gets in, the filler will hold it there, creating the perfect conditions for some really good rot....

I agree with Starleen that with the axle positioned less than 40% (37"/96") of the body from the back, you'll get a nice tongue weight.
