Currently have 8500 miles on it. Just got back from 2000+ mile trip -- Amarillo to Walsenburg, CO to San Luis Lake SP to Navajo SP to Durango to Albuquerque, NM to home. Towed 4400 lb (600 on hitch) travel trailer @ 55 mph (my choice -- was more comfortable driving 55 than faster -- I'm 67 yrs old!). Went over 3 passes (Raton: 7800 ft, La Veta: 9400 ft, & Wolf Creek, 10,868 ft) -- 12.5 mpg while towing. Up passes at 55 mph until speed dropped, then reset cruise @ 40 mph & stepped on throttle until transmission dropped into 2nd gear; walked the passes @ 3800rpm @ 40 mph in 2nd on cruise with no problems at all. Absolutely fantastic truck. Has done everything I've asked of it & more.
