My buddy had a power steering pump issue on the way camping, so I took his camper and gear the last 30 miles. He scaled 13,300 that morning in an 07 QC DRW. I am pretty sure I was pushing 14K with 9K on the rear axle. I could only get the air to 94psi with my OBA (I need a new pressure switch), but never topped 20 mph.
