I'm rather fond of them. I bought my first one in 1988. It was one of the first made for the 89 year run. After a mere 306,000 miles, I bought an 06 which I still have.
I "only" get about 18 plus unloaded around town, driving up and down the foothills, etc. we have here. With my fully loaded Lance Camper, and towing either of my Jeeps, I get about 13 mpg. unless I'm climbing grades alot. I no trouble keeping up with the traffic when so loaded even going uphill. E
