short list of late model TH's we're considering.....help?

Of that list only the Grand Design is warrantied for full time use. Not that you plan on using it that way, but I think it says something about the company and build quality. Most others specifically will state they are for recreational (weekend) use only.

Having JUST looked at the Voltage side by side with a Cyclone (which I know isn't on your list) I would buy a Cyclone if you can find one in the floor plan you want. The dealer even admitted that as nice as the Voltage is, it isn't built as well as a Cyclone even though it is higher priced! I was once in the market for a TH and I looked at almost all of the brands over a year and kept coming back to Heartland Cyclone. Just my .02.
