I would suggest that the OP make sure of his actual height. He indicated he was at 13” 8’ which is, I believe close to what the US Interstate highway system claims is the minimum which is 16 rural and 14 urban.
Sometimes it is a two person job to get an accurate measurement of rig height. With any tall rig be especially careful when pulling into gas stations that have an overhead cover. I like to put a post it note on my dash, showing my height in feet and inches as well as metric for when I am in Canada.
One trip we were in Fairbanks and one of the Prevost RV Clubs from the Lower 48 was at the campground. Those H-45 rigs are pushing the height limit. LOL
Also watch out for low hanging limbs in campgrounds or boon dock areas. The trip is very doable, just be watchful.
