Replying to my own self here, but as a means to provide an update to the 'Chalet #0206" situation. On one of the rare times when my Google email alert setup for any new results of these worked, it worked this morning to alert me to these guys' hours-old Youtube video of the 'repair' work they are doing to it. There's other vehicles in the video, so viewers need to skip over those to see what's going on with this rig. Yep, as I suspected, floor and sills rot requiring new sheetmetal. And as sometimes happens, guys working on these do next to zero internet research on these to figure out enough details on what they have. I left a reply in their comment section if they want more info on this one.
Two troublesome things they say in the video, first that it will be 'back on the market,' but I don't know if they've been the sellers since the above re-listing in August or if they bought it from that seller. Second - and far
worse - the narrator guy says the scissors lift for the pop up roof was long gone and they just simply glued the roof down permanently. That, as I said in the comment I left, is a gi-normous resale value killing mistake (If they delete my comment, I did save what I wrote, though).
