Overhead support
Anyone ever here of an air support system for the actual overhead? My father-in-law said he has seen a tube type system, inflatable, which rests on the top of the cab and helps to support the overhead sleeping area?

- Not that anyone cares... I totally agree with the last four posts.

That is the theory, but I was never able to prove it to be true. If it made a difference it was so little I could not tell.- I agree with the above comments. They should not be used on modern trucks as a support. I have seen them advertised lately as improving the aerodynamics of the cab over to reduce drag and increase fuel economy.
- That is 70's tech. The intended purpose was to increase MPG and reduce the purpose effect. They also had them, in a doughnut form, between the cab of the truck and TC. This allowed you to pass through the truck cab and TC. In the 70's and 80's, I have had both. What they did more than anything was rub the paint off the truck and/or TC. You could buy a plastic film to eliminate the rubbing. I don't know what looked worse, film or paint rubs.
Wayne - The roofs on trucks made in the last 15-20 years are made from very thin material. They will buckle from hand pressure of applying a fresh coat of wax. There is no way they will support any appreciable weight.
Besides, the cabover doesn't need extra support. It's designed to cantilever out over the roof of the truck and support significant weight.
