What is your rig height?
I’m 13’1” on my Cedar Creek fifth wheel. I’ve gone under a railroad trestle in OR that was listed at 13’6” in one direction and 13’4” in the other without touching. The last time, I taped two popsicle sticks to the A/C shroud one at 13’6” and the other at 13’8”. The longer one was missing so pretty close. Was kind of nervous the first time through there. A friend who lived near the trestle mentioned that when the pavement was redone, they spent some effort maintaining the same clearance.
