I have a 2011 Fuzion 322 Touring Edition 3, although it's a little smaller then what you are looking at, I have had no big problems with the unit.
Have pulled it from south Louisiana west to Cali. across north Nevada & Utah. North to Nebraska and pretty much across the south.
Find the build to be sturdy & well built. Used it during a hurricane for several members of the family when the power was out.
If I was shopping for another TH, I would not hesitate to look into the Fuzion again.
As far as Camper World, I have never had dealings with them but I have read many, many bad reviews on service after the sale, just an FYI.
I agree with the Chevy. It's funny because I find that my Chevy is much more comfortable than the other two. I did have a Dodge and the motor was great just the ride was very hard.
I've pulled my rig from Lousiana to Cali., from Louisiana to Nebraska and all stops in between and it has preformed great. My only complaint is the fuel tank size in my 09.
But like the others have said its preference, It's what you like.
