Pulled the 5th wheel from Independence Oregon to Marengo Ohio via Montana, Wyoming, Kentucky, Tennesee and several other side trips. So far about 5000 miles and only issues have been a broken windshield and 3 tires that developed uneven tread wear along the way. We're in Marengo for a week, next stop is Georgia. Old truck has run flawlessly so far, averaging a little over 12 mpg.
