Re: Sherm's family's new skoolie!
The frig in our fifth-wheel is typical of what most RV's have. It can run on AC, propane, and 12V DC. It's not quite as large as a frig one would have in a home, but it's adequate. Our's was made by Dometic.
If you are only going to use the frig while connected to shore power a household frig would be fine, but it would be tough to do any traveling with. I am sure an RV frig like ours would cost more than a basic household frig, but I bet you could find one at a good price somewhere.
Your bus looks great. I will check in often.
