I remember seeing some old photos of the Barth factory showing the construction of the aluminum "cage" but my question is "Did Barth use cross stringers in the walls (like the roof)?". I am thinking of ways to insulate the walls with floam but it won't work if the walls have horizontal stringers. Anyone know the answer?

I guess I'll need a Plan B! I can't hang enough pictures to cover all the holes necessary to inject foam into all those cavities. It seems that the top set behind the overhead compartments are the hotest in the summer and coldest in the winter.

What is not shown on that nice shiny picture is the sticky, black schmutz and pink fiberglass that is applied next.

Is the floor structure aluminum also?

The floor is 2" square tubing. There is aluminum sheeting under this.

Is the square tubing in the floor steel or aluminum

steel

What did Barth use to separate the aluminum sheet from the steel tubing?
