So by Banks, you are referring to a different manifold? Just want to make sure. when I spoke with the previous owner(PO), they said the unit has been taken care of very well and the engine purrs. I wouldn't expect a Po to say anything else if they want to sell. The MH has 62, 247 miles on the original engine. no major upgrades but closets in place of dinnette, and an air leveling system and a rear view camara. I called my insurance company, and it appears that insurance will not be a major factor. The gas milage is not as good as i wanted, but hey, you have to face the music if you want to dance irght? Anyone know were I can find some owner manuals? The PO said they do not have any. Thanks. My name is Hector
