I used blue dow foam on the sides and top. 3/4" in the sides and 2 layers of 3/4 in the top for 1-1/2". That's a R-value of 8" in the roof with 2 layers plus the R-value of your headlinger and exterior covering. I paid around $75 for all the foam I used in a 5' wide by 9'-6" long trailer.

I used 2 inches of the pink sheet foam in the walls and roof and I can't believe how warm the trailer is. In fact, on our last trip, it got a bit too warm and we had to figure out how to vent the trailer without opening the top vent in the cold rain. Thank goodness I put windows in on both sides. I feel confident about staying warm in any type of weather. I do have a small catalytic heater inside to warm things up but I've never run it for more than 20 minutes before shutting it down and staying warm for the rest of the night.

It sounds like you may be a bit too far along now to change wall thickeness but if you can, I'd recommend putting in the foam sheets. I think I paid 17.00 for a 2" thick 4x8 sheet

My insulation was free. A company I do work for had received marble table tops that were packaged in Styrofoam blocks 3"x 3'x3'. I got about 4 or 5 blocks. I cut them up and placed them in the roof. I used their old convention booth which was a kind of corrugated plastic board covered with a black cloth for the interior walls.

I haven't camped in it yet and don't plan on using it in temps below 30 degrees but besides the insulation, it will cut down on campground noise and rain noise. We'll see.

If you live near fernley, nv., Rmax has a manufacturing plant there. You can get end run pieces, slight defects for cheap. My husband did his machine shop addition for cheap. I'm sure other plants do the same.
