I think the stabilizers are going to be the same BAL stabilizers that other Airstream and Argosy trailers use, though the more compact the trailer is, the more challenging it is to find a place to attach the stabilizers that isn't in the way of something else. I bought a set from Out of Doors Mart to add to my Argosy and have LOVED them. I'm not built for crawling around on the ground under the trailer to place portable stabilizer jacks, never mind the bugs/dirt/mud/etc one finds there!
Welcome to the Forums, by the way... we've traded email shortly after you bought the Caravelle, about a fridge I was freecycling.
