Yes, I already have this issue with the van since the ladders are stored on their sides on the roof. When I was up on the box truck roof waterproofing I dropped a tape measure down to check clearance. I will be putting a sticker on the windshield that says CLEARANCE: 10' 4". I have been amazed at the number of places I have to navigate around low hanging tree branches. You would think with all the other box trucks running around (UPS, FedEx, Amazon, U-Haul) those would have been trimmed (or broken off) by now. I'm not sure how legal it is, but I figure I'll be using my Sawzall occasional to make a street accessible.Gonna be heck going through the restaurant drive-thru!
