We also have a Casita 17 and are looking at the Surveyor 186, the version without the slideout. The one thing we are concerned about is the tongue jack. A couple of folks on other posts said they believe the gears are plastic and they had a problem with stripping or binding of the gears. When I turned the handle on the 186 I could feel and hear the gears. It just didn't feel quiet and smooth like the Casita jack or the one on others campers I have tried.
I don't think you find the kind of fit-and- finish quality here that Casitas come out of the factory with. The one we're looking at will have to have several trim problems fixed before we could consider buying it.
Some things, like the cabinetry, were surprisingly nice, and there are a lot of options the Casita simply can't offer.
Hope this helps, and I'd like to hear from others about this tongue jack.
