I am at 13.7 to the top of my front AC (Yes Measured exactly like the photo above) most states allow 13.6 so OP should be fine. I purchased an excellent app called lowclearances.com and I use it all the time to plot my courses. I believe the app is constantly updated from a network of truckers, RV'rs etc.. My advice to you is to be very cautious of railroad bridges and low gas station roofs. I also affixed a Girrafe-GR low clearance device to my roof for any suspicious clearances. My biggest fear is road construction detours that lead you off the beaten path. If I'm ever in a tight pinch to get under something like a gas station awning I will simply let the air out of my Firestone bags and it drops the Fiver nose down about 3 inches. (And as for the height police, I do know that I am too high and there is little that I can do about it without spending $$$) Stay low and have fun all!!:B
