I finally have a chance to catch up on the final build process that went right up to the shakedown trip, so I'll add the additional photos and comments now.
If you haven't checked out the "maiden voyage" shakedown yet on trip reports, here it is:

Well as you might imagine that last week or so was fast and fierce to finish up to a point of being confident the camper wouldn't leak, wouldn't fall apart, and wouldn't fall off the truck. Back on entry #125, I had tried the liner on for fit, so let's back up to there.
If you look at the back of the camper, the liner is very loose fitting, too loose in fact, so it had to be taken back off, and back to the sewing machine. I pulled the material as tightly as possible to the back of the camper, and folded what I could over top of itself, and determined it would be safe to remove two inches, or so, of material. To accomplish this, I undid the seam on the rear of both side panels, removing 1 inch of material from both sides, and then resewing the seams as described earlier.
With hindsight, I would say the most accurate measurement for the liner is taken from the circumference of the camper body, not the lid. There's probably a good bit of allowance here, because, 40 feet of vinyl will allow some stretching if needed. So try for a reasonably snug fit on the bottom on the first try. Mine was still a little looser than desired when I tried it back on, but I had to go with that, because to take more material out pretty much meant another two inches minimum, based on redoing seams, and not having needle holes shewing. From pictures I have seen, it looks like the fit on the lid is pretty snug, requiring some stretching, when installed, looking at the photos of Ski's ATC build thread.
Here's the difference when I brought the liner back out to the garage and tried it on. The fit fit was close enough to live with, and over time will likely shrink a bit little by little as the fabric ages. So, game on!
First I removed all the staples and screws holding the rooftop sheet metal down, and went around and snugged the headliner material one more time, added more contact cement where needed, and folded it up over, and underneath the sheetmetal, trying not to cut myself in the process.
Next, I cut, I think 4 1/2" strips of left over vinyl material, enough to go the length of each side, for the Arctic Pack to be added later, sewed on the Velcro, and attached these with staples, before putting the completed side liner back on. I used 2" loop Velcro material here. I would leave a 1/4" space of vinyl above the edge of the Velcro when installed, as the trim ring will use that up when it is installed later. Here's those shots.
