We're 13'3". Big rigs are 13'6". Dunno where all you like to go, but suggest you get a GPS so you can program in your height to help keep you off roads where you won't fit. In Denver, there are bridges on I-25 with low clearances on the edges and trucks gotta run the right 2 lanes. If you get off the beaten path, you gotta be careful.
I downloaded an app called Allstays Camp and Rv. You can put in filters and they'll show up on the map for some pre-trip route planning.
I even bought some abs piping and a couple joints and cut the assembled unit just a little taller than my rig. I don't trust bridges that are off the beaten path...especially on gravel or dirt roads.
