It is an interesting idea, and one could make it look better, but I'm thinking of a fold-up/fold-down porch thing with a fold-out ladder stair situation to wherewith an awning on the popup one has a nice shaded veranda with an awesome view. You can buy used flatbed trucks like this, cheap, diesel, all over the place, and used popup trailer campers are affordable too. I know where there is a nice older Jayco, always garaged, in mint shape, rooftop A/C for $500 cash right now.
