I previously owned a 1979 Jubilee, and I believe there were not too many made. If my recollection is correct, I think they were manufactured for only about 2 years; 1979-80 in the last years of Trillium's operation.
I camped with the unit for 5 or 6 years, with no major problems - a few small leaks
in heavy rains, all of which were found and fixed. It was in fair condition when I bought it, requiring the usual replacing of tires
, weel bearings, leak repairs to roof/roof vent, minor rewiring, lots of clean-up and paint
and other cosmetic items. I had to replace some rotted wood in the dinette area caused by leaks
in the belly band and taillights, but this is common with older trailers.
When I sold it I got pretty much what I had put into it, not including my labour. It was a fine unit and you will seldom see another one in your travels.
