You'll tend to see a lot of Olivers ended up in Arizona, and Lake Havasu in particular. In part because the patriarch of Oliver (Jim and his wife), who the trailers were their dream passion, wintered there. They kept several Olivers at their home there, and frequently took them down to nearby Quartzsite. They sold a lot of them simply by word of mouth and sitings.
We're also helping some friends in Lake Havasu sell their Oliver (which is solar
powered) - that they bought simply because they saw Jim showing his off in town. I'll be putting up a separate listing for it here.
Having two Olivers on the market at the same time - very unique situation!
Best wishes in find a new home for your redrover - sorry that your travel plans didn't work out
