I-70 from Grand Junction CO to Denver CO

We will be driving through Colorado on I-70 from Grand Junction to east of Denver on our way to Michigan in May 2018. The trip planner shows about 5 tunnels on this route. I have contacted CO DOT about elevations in these tunnels. The specs on our 5th wheel say our height is 13-11. I believe we won't have any issues with clearance in the tunnels. Has anyone traveled this route? Is my assumption about clearance for our rig correct?
