Teardrops n Tiny Travel Trailers

Hi everyone, long time lurker here. I picked up a 7X16 featherlite v nose to convert into a mobile hunting base camp. We travel from WI to WY, MT, or CO every year to hunt mule deer or elk. Plan on taking the trailer this year instead of my old camper. Still putting together plans for the wiring and layout, I'll start a build thread once we get into that. It needs a new floor but right now I'm getting a lot of different information and can't sort it out. Some say you need treated, some say treated is bad for aluminum, some say marine grade is a must, etc...

What are the opinions of those who have done this before?

Thanks!

The current PT wood chemicals will corrode aluminum quickly and badly.

IMO, you do not need PT unless you will be getting the plywood wet from the inside a lot, having water sit and puddle and soak in.
I would use a good exterior grade of plywood and undercoat it. Easiest to cut and fit the floor, remove and turn over and then undercoat. Reinstall when dry.

Marine plywood would be for the compulsive worrier type, IMO.

I would put in 3/4'' plywood and spray the bed liner coating on it before installing and then spray it again after I installed it. no need to coat the inside unless you are going to be tracking in lots of water then you might want to coat the inside with the garage floor paint its tough stuff

I will get some good quality exterior grade sheets and give it a shot. I'll start a build thread once I get rolling and have some pictures. Thanks!

Georgia Pacific has a 3/4" T&G subfloor called DryPly that is made to withstand rain before the house is roofed. It's a little hard to find, Home Despot doesn't seem to carry it any more. Used it on a truck conversion, it stood up to a lot of abuse.
