'95 Fourwinds RV with 460 cu in V8 (7.5L). Banks headers, exhaust and cold air intake. About 9 mpg but traveling in style.

And for when you arrive and don't want to use a 27' RV as a run about:



This 50cc scooter sits on the trailer in between the hulls when travelling. Mods include a performance resonator exhaust (worth an extra 2mph) and pumping up the tires to max pressure (that also got another 2mph). Not very fast but a lot of fun <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" />
