I can't address either of your questions specifically, but I just wanted to mention (which you may already know) that there are a few trailers out there that are "clones" of the Cloud
. They won't be exactly the same, but there is a very strong family resemblance.
I'll list them in order of how many were (I think) made:
Both the Burro
and the U-haul
have more extensive fiberglass liners (all furniture and walls except for a front-to-back center roof strip) than the Cloud
(which I believe has a half liner?). I will guess the Companion does not have a full liner, but I'm not sure (I have seen them with carpeted walls).
I *know* I speak for more than myself when I say we would love to see your rig
