Thanks for the information guys.
A little thinking out loud here...
I like the idea of a folding A frame foamie camper because it would be light weight and easy to tow. Because I'd be camping by myself most of the time, I'd need help opening the roof evenly and holding the roof open while I put up the walls. The roof would be very light weight but over 6 feet wide and about 7 feet long. So the struts would not need a lot of pressure but it may need to be extra long. Or if I put the struts closer to the hinge, it could be shorter but it would need more pressure. I'd have to find a sweet spot for that. I also need to figure in the possibility of having to open the roof during windy conditions and give it extra strength against cross winds when it isn't supported by the walls.
I don't know about you guys, but for me, the challenge of coming up with the design for a project, and trying to think of how I can make something work, is more fun than building the project. I learn a lot and I get to expand my imagination.
Never argue with an idiot. They will bring you down to their level and beat you with experience.
