I would second that. GM TBI is very easy to set up and being a motorhome setup you already have a nice stand-alone style harness. If you plan no mods to the engine the TBI will do better than any carb as far as mileage and changes in weather conditions. You will need to add a O2 sensor bung on the header collector. The only other thing you may not have is a VSS signal which you can easily add a pulse generator on the speedometer output on the transmission.
