Best ways to insulate, waterproof and seal the floor

[backstrap bandit]

Actually they use arsnic for treated wood that comes in contact with ground and the other stuff is light green or blueish is salt treated for above ground use and also don't cover treated wood with aluminum the chemicals in the wood will eat thru aluminum

No worry the pressure treated plywood. Self adhesive flashing and tar paper are between the pressure treated plywood and the aluminum skin or the steel frame. I wish I had used 1/2 instead of 3/4" for weight reasons.

Hey buckshot I too was thinking of skinning the bottom side but not for any reason but hold insulation to floor( I just hate cold floors) and to make cleaning under side easier I'm just gonna cut Aluminum coil stock left over from house job into squares and but up with screws that way if I have any problems with anything under it I can remove it easily

You won't have a cold floor if it's a TD and you have a mattress in it..the mattress will insulate YOU from the floor.

Yeah but I plan on using mine before I get the matress I have to have a custom matress cut about 300 for the foam

I tossed my yard sale lexan under the floor



Then my 1/2" osb floor



After a couple of winter campouts I decided to insulate the floor. I placed 1" closed cell foam board and laid over a 7/16" osb subfloor over the foam to protect it. To install it I simply placed it in thru the side door in 3 sections and it just floats on the foam.

floridadon & Henery Hawk,
I have also been storing up my build STUFF. A possible change of plan may have me choose to have a trailer mfg company here is Ocala do the build with my blueprint. Then I will have to put the
interior together. I will have to get some plan on the shower install along with other plumbing and electrical both 12v and 110. Should prove to be interesting.
Have fun,
buckshot
