Designing a clamshell

Trying to design a different pop up camper.
Seen some close on here. My desire is for a really light but roomy trailer. But also quick and easy set up.
Basically a teardrop or angled front that is hinged.
then the back would lift up, would have tent material sides when open.
Looking for 12' long, 6.5' wide and at least 6'2" high at the 54" mark back from the front and at least that high or higher for the rest of the camper.
Any help appreciated.
