Quality of Class C

I wouldn't say that only having one AC is a deal stopper IF IT IS POSSIBLE TO ADD A SECOND AC. my 32 ft bounder came with one AC. I added a second smaller one in the bed room vent, since it was cheaper and an expendable unit, I ran that if there was poor electrical service, etc. the main advantage (other than capacity) in having two units was being able to once cool, to alternate the one that was on based on where you were in the RV. just be sure to take the $$$ into account.

Off the cuff, we always say choose the one with the floor plan you like best, and also choose the one you are sure has no roof leaks. If one has been under covered storage that would be a big plus. Itasca is made by Winnebago which is generally well respected. Oh, one other REAL important thing. If one has two AC units buy that one all things being equal. If both have only one AC don't buy either of them. It's really important in a 31 foot rig. Especially you living in Florida.

thor vs winnie, no doubt winnie. but unlike the pictured one, prone to eventual leakage, etc.
