I think we're all happy to have both of you here and are definitely interested to see your progress. All the same, I think you'll find more info at toyotamotorhome.org
. Like here, they're also not
a slide-in camper site, but at least they're very familiar with Sundraders over there. We have some advice for some slide-in campers, since a few of them also make molded fiberglass trailers (Bigfoot, Northern Lite), but Sunrader never made a trailer (as far as I know) so there's just very little knowledge about them on this forum.
Good luck! The Sunrader was always my dream motorhome.
