How thick are your inner walls?

[RoadtripsAndCampfires]

We made the insulation the number one priority in our build. It has definately paid off in the comfort level. We have a cargo trailer, not a van so it was easy (fairly) to do.

All our wood was primed and painted to prevent future warping, insects and mold as much as possible.

When we did add wood we used the thinnest available for what we were working on. Therefore, some of the wood is thicker than the others depending upon its use.

We used 3 indoor doors which we bolted to the floor with metal brackets to make "semi-walls." The forward section of our trailer is part of the bathroom as well as the kitchen sink and other kitchen stuff. One door separates these two areas yet is open where the door ends. Another door is on the driver's side of the trailer at the end of the bathroom. On the other side of that is the refrigerator with 2 big cupboards above we use for clothes. The third door is on the other side of the refrigerator and also serves as the right side of the closet area (there is no front door on the closet but there is a shelf built above it. The open closet has a pole at top and half the closet gets jackets hung up and the other half is where we put the floor air conditioner with a 6" vent to the outside.

These doors are hollow, you know, the cheap kind they put in apartments and other rentals. They are not real expensive and we are very happy that we thought to use them. Oh, FYI, the other side of the closet is next to the bed and we just used 1x2's. The A/C has air space behind it and on the side by the fridge wall. There are no vents on the left side of the A/C so we are able to use that floorspace for items. Our water tank is in a box in front of the closet and the A/C air flow vents sit well above the tank.

I have a conversion van, and after filling in the windows with polyiso and bringing things even, I used simple i/8 trim sheets.  Nice and flexible.

My insulation varies from 1 1/2 inch to 3 inch.

Very nice pics that show how simply it's done. Thanks for sharing them!

I love your process and the build must look very nice. I especially like the ideas with the hollow doors. Your preparation of the plywood is very important for durability and comfort. Excellent planning!
