Finally Started! Your Thoughts.

Yeah...I finally figured I would give it a try after debating about if I should go buy one or try to do it myself.
First I went for supplies...
This is how far I got the first day...
Well my question is... Should I add a couple of more cross supports or should this be good with the 3/4" plywood? It is 5'x9' 3/4" Birch plywood and 1x2 oak frame boards. I will be building my own trailer after the teardrop is almost finished.
Thanks for any input....I don't want to over build or under build.
