HF trailer ordered...got some floor questions. :)

[Eric Adams]

I am looking at my flooring now that the trailer is ordered. I figure I had better stay 1 step ahead. I plan on putting plywood down first, then a subframe lined with pink and mylarbacked insulation, then plywood on top.

4 questions:

1) What thickness of which kind of plywood to use on each side? I am thinking thicker on the "floor" top?

2) recommended insulation for the floor?

3) Recommended substance to cover that bottom sheet to keep water and such from rotting the wood? Roofing tar?

4) recommended wood type and size for the framing?



Keep in mind that I'll probably shop for this at Lowes or Home Depot.

Thanks guys!

I used 2 by 4's, ripped, for the frame. That gave me 1-1/2" for foam insulation. This may seem like a lot, but, I will use the camper more in the fall/winter than in the summer.
I used 1/4" ply on the road side, 1/2" on the top. I got pink board from Homer's.
I sealed the roadside with three coats of unfibered roof coating, also from Homer's. I used about half of a gallon.


I built a five foot wide tear, so I spliced down the center.

Nice!!

Fibered coating bad?
What kind of plywood? Regular or marine grade?

Almost forgot, air nailer, stapler or screws to attach most of the body? I am thinking, wood screws? They make any screws with glue on them like they make those nails with glue on them?

Unfibered, it's easy to apply with a paint brush. I used exterior grade ply, plugged and sanded one side. For most of the assembly, I used screws with glue. Regular sheetrock type everywhere except the bottom of the floor, and attatching the walls to the deck. I used treated decking screws here.
I used an electric brad nailer/stapler to attatch the interior paneling,and the headliner/ roof skin, with glue also .

Sounds great. Plugged?

Plugged, the knots and other flaws in the surface veneer are removed, and plugged with a patch. The whole sheet is sanded smooth. This ply is great for floor underlayment, or jobs that get painted, etc.
