I recently bought a 6 x 12 enclosed and don't care much for the bare plywood floor. Should I paint it, put a roll on liner or something else?

 

I'd go with a roll on liner product of some sort as paint can and will get slick and you don't want that. Or you can add in some sand to porch paint and end up with a non-slip surface.

 

1/8" diamond plate.

 

Mine has carpeting.

 

mine has epoxy paint with speckles

 

I always used clear polyurethane. Two coats of it will last a lifetime of abuse.

But with my latest one after the polyurethane dried I did the floor with 1'x1' black and white stick on tiles. Looks great.

 

I have outdoor carpeting in mine. What ever you decide just make sure its not slick

 

Diamond plate, epoxy, and urethane will all get slick if water or oil somehow gets on it. You don't want that in an enclosed space like a trailer.

 

I used black and white vinyl flooring.
Working out great for me.
Hand painted the ramp. Extra sand in the black for traction.

 

Trailers are for boats.
