I posted about this idea of towing a foamie with a maxi scooter on one of the big motorcycle forums,
https://www.advrider.com/f/threads/towing-with-a-maxi-scooter-silverwing.1576045/page-2#post-45257695, and received some worthwhile feedback. In addition to the obvious, keeping the weight down, they brought up the idea of the “wind sail” effect of my current mini foamie design, which corresponds with the Canadian Helio trailer size and shape:

Based on this feedback I decided to use the arched roof xps sheets I have already built for my originally planned full size vardo build, put off that build till after this one, and make the roof and front end of my mini foamie camper more like the ingenious FoamStream here on tttnt.

I’ll maintain some of the front to rear height change of the Helio design but incorporate the arched roof and front end of the FoamStream to make it more aerodynamic for towing with my Silverwing.
Since I already have 3” xps arches and sheets, I’ll go ahead and build this mini version out of 3” xps. Yes, it’s definitely overkill, since I could do it with 1”, but it’s R15 insulation value and it’s what I already have on hand, since I found it relatively cheap on Facebook Marketplace for my vardo build. Plus structurally it’s many times stronger than 1”.
So my exterior width will be 54” and interior width 48”. Exterior length including the 3” foam will be about 80” externally and 75” internally. The rear wall will be a used 38x50 Rv door I found on Facebook Marketplace for $75. Surprisingly this door and frame is very light weight.
