Your reply's will most likely get you many pro's and many con's on this unit.  Some who have owned one and some who have not.  Here's mine - lol
I own a 37', 08 Gulf Stream Supernova 6372 with 41,000 miles.  I get 8 miles to the gallon.  I tow either a ford escape on a dolly or a 20' trailer with motorcycles and atv's.  
We "half-time" in our unit.  We spend 4 months each winter in Florida and 2 months each summer in Colorado plus various short trips throughout the year.  
The above kinda gives you an idea of how we use the rig.  
I am overall happy with the rig, a grade of B+.  Love the body style, floor plan, capacities, etc.  The only thing I would grade it down on (hence not an A)  is the torque and the ride. 
I corrected the ride by adding better shocks on the front and airbags on the rear which gives me the ride I want.  If the unit your looking at does not have these options, it's easy enough to make the change but relatively expensive.
As for the torque, it is satisfactory for me except when we are running around in the Colorado Rockies.  I've never encountered anything I couldn't make but I've definitely stretched the power.  
This is my 4th rv and I feel the house durability and the International Chassis have been above average for rigs in this price range.  
PM me if you want additional info.  Good luck with your decision
