I would skip the genny and do what Joel does. Many dealerships will add the genset in the campers they purchase for the lot as it is desirable by many. I have one on my Arctic Fox,and only use it for running the microwave or AC. You will need the genset to run either of them as the truck does not produce enough amps without modifications that will get expensive. Best to see where you are first before making any other purchases. Remember this is a truck camper and not a travel trailer.
