Jwsmith, welcome to the forum. There is a lot of great information here and a lot of great people willing to help out.
We had two portable refers in our last Bighorn. One in the basement for cans of refreshment and one in the laundry closet that was used for overflow from the kitchen refer. The freezer worked OK. but had to be careful not to freeze the stuff in the refer compartment.
Measure before you buy.
Be sure to check out the WI rally on the Portal Page as well as the Heartland Owners Club.
Peace
Dave
