Razz, sounds like what you need is a mini-FoamStream ... could be built really Light !!! Very aerodynamic yet roomy inside ... theoretically ...
You know , there’s something that just makes good sense by going SIMPLE !!! Repairs...

After my little hail storm incident

, got to thinking about how to repair it ... very simple to do (especially since it’s fixing itself) compared with other alternatives which would require extensive repair work to restore. Aluminum would have been looking like a shiny cheese grater , replace that ... fiberglass , would be broken /cracked , replace that ... wood , meh !!! Seems the simpler it is , the easier it is to repair ... Cheaper too !!!
Ps. Since my Foamie has chosen to fix itself , that’s all well and good , but should actual damage have occured , where the canvas was broken through , it still would be an easy matter to fill the divots in with some spray foam and slap some more canvas on top ...

Simple !!!
