So far all I see is references to length...do NOT forget height. Your 10' 6" RV will not fit under the 9' 8" drive-thru at the local greasy spoon.
My recommendation is to take the RV to a surface that is level. Measure from the highest point of your RV to the road surface. You will probably have to hold a level from that high point, so that it hangs over the side of the unit. Once I have that measurement, I like to add an inch or two (just to be on the safe side). Then NEVER, EVER go under anything that does not have clearance for you to fit.
Do NOT base you height on the manufacture's spec sheet. Like weight, they are a generic number based on general assumptions. This is especially true with travel trailers that are assumed to be level...when in fact, you may be towing a bit nose/tail high, which changes the clearance numbers.
13'6" CLEARANCE means 13'6" will fit. 12'8" means 12'8" will fit. Clearance numers tell you what CLEARS, not the actual height of the object. So if you stay under your clearance measurement and hit the obstruction...someone else is to blame.
I will not discuss New York in this post....I don't want to scare you.
Plus remember your under-carriage clearance. R/R tracks, curbs, etc... You don't want to wipe out your plumbing.
