Here’s an idea for a Bigger Foamie , something that could be pretty easily constructed over a minimum framework ( wood or PVC ) and still be LIGHT enough to be Fun to tow , and provide a larger space and not be a burden ( <2000lbs.)
Lots of room for different window and door placements , and you could even have the galley in the back , right next to the internal power supply ( Solar Batteries/inverter ) … After all we have to keep the “ballast" cold in the evenings eh !!!
Solar panels on the roof could be set up/tilted several ways , or lie flat for traveling … That could provide a Lot of power for the evenings with a couple DD or GC batteries for energy storage …
The Bigger Foamie trailer , the better the Engineering required , and the necessity for more careful craftsmanship …
Basically it's a BIG Zephyr ( mentioned elsewhere) , but the much simplified framing style ( boat ) would be appropriate for both . JMHO …
Warning : This is Just an IDEA … No reason to PANIC … (as yet? )
