Had to look up that Lil Snoozy - I see that you are looking for an all fiberglass trailer (Casita/Scamp), not a Fiberglass siding trailer like many of the toy haulers. I've not seen any fiberglass cap toy haulers so can't help there. Your comment about wanting to avoid propane in an RV as being dangerous made me look twice. Good luck on that - I think you may need to change your criteria a bit. I suspect they are scaring you away from propane because they don't want to provide it (Probably for insurance reasons).
Other short toy haulers to consider might be Airstream Basecamp, WhiteWater, ATC or Livin Lite, but none of those are clamshell glass trailers, and all will have Propane, because, well, they are RV's. I suppose you don't have to use the propane if it bothers you.
