No I don't think so, given the trails selected. Lippincott is not a problem and I think the descent from the Salt Tram if you elect to do that on the last day should be fine as well. No one had a problem on the last two trips through steel pass or mengel pass w/o sliders and you would likely need them there more than the trails I've selected. If we were going up Echo Canyon, I'd say yes sliders and full skids, but I don't think I could get my dbl cab through there and down the other side w/o body damage and I'm kinda partial to straight panels. :sombrero: THat said I may have a set of sliders on my rig by the trip date, more to use as steps and door ding prevention as many of the people in my lot at work are a$$hats.
