I'm very interested to see the progress of this.
I contacted Enduro campers and have yet to receive anything back from them.
Their website has some minimal information about build design but overall seems pretty sparse.
My concerns with the supertourer are not having any isolation between the habitat and truck frame. Flexation and rough roads do wonderful things to boxes on trucks. I'm curious how they've mitigated the impacts of terrain changes over the lifespan of a composite walled camper. This design is a world away from a topper on a truck bed.
I'm also curious how fiberglass reinforced plastic paneling holds up to the stresses of overland travel. I know total composites, companies like OEV and bison overland use composites, but we the consumers can be getting very different products that are grouped under the term "composite construction" and they most certainly are not all the same.
Most of what I've read looks like you need backers and Additional support systems to maintain structural integrity on installations that are not mobile, and designing exo skeletal structures comprising of aluminum rails only solves half the issue.
Fiberglass reinforced plastic can't handle heat at all. Like not even a little bit.
It becomes brittle and can crack or fail with exposure to heat, the sun or other ultraviolet light, which means a coating must be applied and then maintained along with all the sealants and glues that hold together the structure.
According to the Enduro supertourer pages, they have composite panelling on the entire structure including the roof and floor. Structural monocoque means their is no subframe system, beams or underneath system other than the shell itself to support everything this is comprised of, and using fiberglass reinforced plastic with little to no signs of wear before failure seems like a sketchy idea to me, however I would love to be proven wrong, as this is a really cool design.
If this idea was executed in a welded aluminum or sheet metal frame I would have already put a deposit on one. Even better if we could have hard sided pop up walls and aluminum substructure
