Well, now I'm discovering even more interesting things about my Boler! It looks like a PO replaced all the fiberglass seats and the couch base with wood. I didn't know they were supposed to be fiberglass!
The rear dinette/bed base is all plywood that has been painted brown. I'm actually happy about this because I think it will make it easier to remove the water tank, which we will never use.
It also will be easier to convert the front couch to a dinette, as I don't have to worry about fiberglassing anything.
I don't know WHY anyone would do this, and I'm sure it adds to the weight
of the trailer, but I'm still very happy with my little trailer.
