I was referring to having to rev it to 4000 rpm's in low/low to move it up some trails, I should have phrased it different. The truck is underpowered at altitude or steep climbs. I bought it for off road use, meaning in my mind trails and two tracks, The truck does not do 4's (trail rating, 1-5) with the camper on it. I thought I could when I bought it, a mangled rear end convinced me I can't.
I love the camper, but I am not a national park camper nor do I like to lots of people around me, which it appears the camper is best at. I would have considered purchasing the new Colorado with the diesel (can not afford it) or swapping in the new Cummins but I live in the peoples republic of California.....
