Here's a little info on it. I recently bought it from someone in a rather remote city for a excellent price. He had fully restored it (having brought in parts, and even a new chassis from all around the continent).
that it was put on a brand new chassis with new wiring and electric brakes (Most of the remaining few for sale have major chassis problems and are at the end of their chassis lives, which often warps the shell).
that it still had the 3 crucial main supports in it so the roof is not compromised with micro-fissures which eventually lead to collapse and total failure ((a) those twisty bars which hold up the roof via the overhead cabinets, (b) the closet which is actually a roof support, (c) the vertical bar beside the door). Too many of the remaining ones unfotunately have seen these removed or modified, which has resulted in fewer and fewer Bolers on the road each year.
The interior ensolite insulation was still intact (it doesn't decompose and remains as pristine as the day it was made). It was designed by NASA to prevent condensation and mould inside space capsules. Too many Bolers had it removed which has lead to problems, but this one's ensolite was all still there, making the interior wall as good as new with a little paint.
It's all one piece. Most trailers have a seam separating the roof from the walls. This doesn't. So there are never any leaks.
They have steadily been increasing in value. The VIN # is actually only 3-digits (Government registries wasn't quite sure how to process such a low VIN # for plates). Because it's so vintage, so light and well-built, there are a lot of Boler enthusiasts and are a hot commodity. Consequently, with fewer and fewer of them on the market in good conditions (for all the reasons I mentioned above), the value of Bolers seems to go up every year by about $500 to $1000 (depending on the city). And they're great for towing (So light that I don't even feel it behind the truck). It made for a great little investment which I could also have some fun with (Whereas newer ones for a similar price tend to quickly devalue, and often develop leaking roof or mechanical problems after several years).
Just seemed like an all-around smart little thing to buy. Am looking forward to having fun with it :)
