Jagular7,
You bring up a number of things that I have been wondering about. My
trailer does have a solid deck that has very short 1/8" ribs maybe 3/8"
apart, so full contact isn't a problem. There are however no drain holes,
these could be easily added.
The trailer has a 6" tall lip on the front and 2 1/2" on both sides. My thought was to build an aluminum frame that sits inside this lip, attaching the actual floor of the td to it, so there would never be any direct contact wood to floor. On that support frame maybe 3 or 4 runners with like? cutting board material so it would slide. Actually though, you make me think that if I just allow the td to be say 6" or even a foot longer, overhanging at the rear. Then to get it off, just drop the tongue down which would lift the rear, place supports at the rear then lift the front enough to slide the trailer out.
Maybe if you saw my trailer ( #1683 Featherlite ) photo in orig. post above. It's all aluminum and weighs 380lbs After I removed all the removable parts, i.e. ramp, sides, front I was surprised how heavy these pieces were.
Thank you all in advance for your help..
