Back in 1995 my wife and I visited the Roadtrek Factory in Canada,can't remember the name of the town, offhand, but we were very impressed with their product.
Although we did not buy one, instead we purchased a Pleasureway, also made in Canada (Sascathuan). only because the model on hand was the one we liked.
As for information about Roadtrek, simply go to www.Roadtrek.com
and you can get all kinds of information on their web site, hopefully that will answer all your questions.
