I guess my OFF-ROAD POPUP trailer with 15-inch tires is around 6-foot... I can almost look across the roof line standing on the ground. Then I have the Air Conditioner on top of that...
My only worries is pulling through a McDonalds Drive thru and my Antennas drag or I get caught in a tight turn on the Forest Service road back in the woods somewhere hehe...
Use to pull using US82 going from Ala to Wichita Falls Texas alot. Texarkana on the Arkansas side has a very low underpass under a railroad track crossing and the underpass is all beat up from high trailers trying to get through... Plainly marked as well... I guess folks always think they will just make it through...
Yup - size does matter... Small Size in my case...
