I'm planning a trip to the San Rafael Swell (and then on through Capitol Reef and GSENM) and plan on using the interstate 70 underpasses with my truck camper. I need about 8'6" of clearance. Has anyone here used these underpasses with a popup truck camper? They're just culverts for a waterway but the dirt roads use them to cross I70. I've seen lots of pictures of jeeps going through the culverts but I can't estimate the height.
I'm talking about the I70 underpasses in the Black Dragon area and the two in the Head of Sinbad area.
