From their web site, they appear to be built like a fiberglass boat.
A uniform first layer of gelcoat is critical. Laying in spun/woven mats and wetting it out should be the step. Do they use more than one layer ? What type of a mat are they using.
I would be surprised if they used "chopper guns" to build up thickness. These are fast but nowhere near as strong as glass matting.
The floor obviously has to be thicker/stronger that the rest. Typically this is done with some kind of "core" material. Balsa wood was used (perhaps still is) for many years until people realized that one tiny crack would allow water intrusion that would rot the wood. Repairs were difficult/impossible on some boats.
Also pay attention to home the shell is attached to the frame.
They look like nice trailers ! They do offer several factory "premium" option that no other TT offer. I would like to hear your report.
