Is this one of the models people here say ...

Based on the short time we've had our Bay Star, I agree that you want two AC units if you are going to be in any hot summer weather conditions. When we were researching motorhomes, we decided that with our budget, we had to buy used and for the money, we would stick with motorhomes made by Tiffin, Newmar, Winnebago/Itasca or Holiday Rambler (2008 or older). That was our preference and we know that there are a lot of happy owners of other brands. All I can suggest to the OP is that they look at a lot of used motorhomes and compare carefully the quality of furniture, cabinet work, tank capacity, number of AC units and generator size.

We have a 7500K generator, and it has been great to be able to run both AC units and still be able to the microwave or run a hair dryer, toaster, etc.
