I’m considering installing some drains on my trailer and wanted you guy’s opinion. Every time I spill something or want to wash it out it holds water. I can disconnect the trailer and jack it all the way up but that’s not very convenient. I’d like to be able to wash it out regularly.
My dad is a life long Carpenter and he says not to do it bc of the moisture barrier. My point is the barrier doesn’t matter if it’s constantly wet inside.
The flooring is 3/4 plywood untreated with a moister barrier on bottom side. It’s not coated. Bare wood. I’d liike to cost it if I ever get a few days break.
My 20’ enclosed haulmark has a factory 3" hole in the floor near the bulkhead for the wires that run from the electric panel to the generator plug up front. Diamond plate floor on top of plywood, granted everything drains in the opposite direction of it. Could just drill a 3" hole and buy a pack of rubber test plugs, or go smaller and get some rubber marine drain plugs.
You’ve probably already thought of it, but I would just make sure you rinse the underside as well, so no sh sits on the frame rails and corrodes the bolts.
