Popupportal has been a wealth of information! Thanks to those who suggested it.
We are going to pick up the camper (again!) this weekend, as it sadly broke the first time we went to use it so we had to bring it back. One of the bunk ends wound up going off the track. We banged it back into place so we could close it up to bring it back, but it needed to be looked at. It was covered under warranty, and will be replaced someday but JAyco has a lot of need for this track right now (telling me it's a more global problem!). It looks iffy as to whether or not we'll get it fixed before our week off grid in early August. We are told we can still use it as is, but I'm less convinced than my partner is. She's optimistic that we can still use it...
So, that part was a bummer, but for the few days that we had it set up in our driveway we loved it!!
