Lance, there is a couple of discussions presently going on about traveling with a residential frig.

Can it be done, You bet. You need to understand the current requirements the frig has, you will need a inverter to operate it while not plugged in.
If you do any dry camping, IE: no shore power, probably not a practical option. If you only travel from the house to the lake 2-3 hours, probably a OK thing.
