Great find Donna, thanks.
The truck-based RV (the "Wothahellizat" - sound it out!) in the link is not the one in this topic, but is of the same general type - camper bodies mounted on high-mobility cab-over-engine truck chassis. They are basically unknown here, but there are lots of European (and Australian) examples. They have the trucks there (6x6 cabovers are virtually non-existent in North America), and apparently some people have a need for extreme mobility in an RV. The Wothahellizat is kind of opposite to our trailers in some ways, but I guess it would be great as a mobile wildlife observing platform in open country, such as the African plains or even for polar bear watching near Churchill, Manitoba (even a polar bear couldn't reach that platform).
At an RV dealership in central Alberta, I saw a camper body on a Pinzgauer, which is a very small European 6X6 truck built for military use. I knew of the Pinzgauerhad, but had never seen or even heard of one here in Canada, so the camper was a surprise. It was brought here by a European couple to tour North America, and left in storage.
The Top 10 list does have trailers, but no moulded fiberglass trailers! It isn't a serious survey of the best in RVs, but it would have been nice to see a classic egg in the mix.
The C-Liner was the most interesting entry in the list to me (I had heard of most of the others). It seems to me to the motorhome equivalent of our trailers - compact, efficient, and a bit unusual. It is unusual in that it is a Class A (full purpose-built body) motorhome in a size range which is filled with Class B (van conversion) and Class C (truck cab and chassis) designs. The 60,000 euro price is not surprising (you can pay that for a camper van here), but still too much for me.
