Out of your area (Sacramento CA), and not sure whether the owners want to sell or not, but there's what appears to be an early 80's 16' Funlite not far from me that's been immobile in a driveway for some time. Looks like it's in pretty good condition (no visible damage, still has all the original tape striping, tires are holding air, etc) - can't see the license plate, so I don't know if the registration is current or not.
Last couple of times I've been in the area, they had a newer Coleman pop-up tent trailer in the driveway, so they may have bought a new(er) trailer and might be getting ready to sell off the HiLo.
I know it's a quite a distance from you, but we went all the way to Kingman AZ from Sacramento to buy our 2307C a couple of years ago.
If you want to try to contact them, I'd be happy to forward the address where the trailer is.
