I think that it is a good deal. I have a 7kw powertech CD7000 in my toterhome. It has a 3cyl Kubota diesel about 11hp. This unit has to 110v circuits but CAN'T be wired for 220v though. This is a good solid unit but it is not one of the really quiet units often used in RVs. You will have a little bit of noise. My generator transfers a lot of vibration into the coach which makes it more noisy. If I were to take some steps to isolate the vibration it would be better. I'll bet that the engine alone is worth $2500.
