I have heard quite a few good reports of factory tours at Roadtrek. Most of them were from the tours given in combine with Roadtrek Rallies, though.
To be fair, we hit them when they were in the process of bringing their painting back into the main plant, and were just coming out of the almost entire shutdown from the economy, so some of the issues are understandable. What isn't understandable was their willingness to ship marginal quality, in an effort to gain market share (which they did). Folks are paying more for Roadtreks than other brands based on reputation, so that is the thing they need to protect the most.
I am actually glad that we already had our C190P when we got the tour, so we wouldn't have had second thoughts. We bought the Roadtrek based on their more efficient use of space and storage areas, so it wasn't an equal choice between the brands based on quality issues. If it had been equal on utility, as it was for Steve, I think the tour we had would have sent us off to see how the tour would be at Pleasure-way and Great West.
We would get a Roadtrek again, but I doubt it would be new, as the prices and quality issues would make it prohibitive for us. There is no way we could drop $90K to get the same thing we pain $58K for in 2008 (very well optioned C190P, model year 07).
