I'm a Fuzion owner and wouldn't have a problem owning another, but if I were in the market today, I would be looking at the Grand Design Momentum line. Slightly more expensive, but when you really pick them apart you will see a huge difference in quality. Grand Design uses better practices in building their trailers, in some cases better components and they are better insulated. The only downside I have found to their product is that they initially only offered two floor plans but that has increased to three this year so they are expanding.
During my search for the perfect toy hauler for my family, we had narrowed it down to Fuzion and Voltage. This was about 10 months before anybody had ever heard of Grand Design.
