So long story short, the canvas fibers keep the wood fibers from failing the paint job, allowing the paint job to continue protecting the fibers. It is a composite where the sum of the parts is greater than the individual elements.

KC, thanks, you nailed it.
Painted wood will fail. sooner or later. Small cracks develop, water gets in, and things get worse. Covering the wood with fiberglass, metal, etc is intended to keep the water from entering the wood. Canvas and paint does the same thing. It encapsulates the wood in a waterproof membrane, and keeps it off the wood.
There are no exposed edges or end grain to soak up water once cracks develop in the paint.
My tear sits outside in Nevada summer heat and winter snow. It's been there for 4 years now, and still is holding up great.
Another small benefit is, I used cheap plywood with lots of knots. It would have been a nightmare to smooth that surface to look OK after paint. Gluing the canvas on covered a multitude of defects, and gave a great surface for applying the finish paint coats.
You pick the way you want to build and do it, that's the fun part of making your own trailer. I know that if I ever build another trailer, I will use the painted canvas approach.

Planning to cover with some Dacron fabric I have but your use of Titebond2 I question. Titebond3 which is water proof would be a better choice. I plan to glue down the edges first then apply heat to stretch the Dacron then apply titebond 3 The Dacron was purchased to build a pontoon boat but never completed.
I like your storage ideas. Curious what does the completed trailer weigh? I am using a HF extra heavy duty trailer w/ 5 lug wheels. I think 1700lbs capacity.
Going with a 64 inch wide trailer (over the fenders) but only have 4 - 7 inches of storage area. Considering headroom, looking at splicing a 12" plywood to make body 60 inches tall and extending the plywood sides to bolt onto the 2 x 4 frame extension.
will post some drawings later.
