I just completed the Indy to Az trip pulling a 12 foot trailer(loaded). The Libby did a great job and averaged an honest 15MPG. The last 60 miles were an interesting ride. Heading from Payson, Az. to Mesa along Rt 87. Big hill @ 6% grade I ran out of motor, radiator and almost speed. Everything worked as advertised and I did make the top running 50 mph, but, temp was almost pegged and the computer cut the RPMs back to take to load off the engine and cooling system. I sure love this little workhorse. So, good trip with a minor issue. I hope this thing will run a very long time. I've gotta do a timing belt very soon, but ya wanna play ya gotta pay !!! Merry Christmas to All !!
