I just read a post in the motorhome general discussion where someone is aking for info on an RV height. I had a good laugh at this when I remember back 3 years ago when I bought our Southwind. It was our first class A. Had an old small tag along before that. Anyway, I'm driving this monster (to me at the time)down this 2 lane road, and suddenly see a train overpass coming up quick.
One of those moments where you have a milion things go through your head, but the most imprtant ones are 1) I don't know the height of this thing, and 2) Duck !!!
Like that was really going to do me any good. LOL So, needless to say I had the clearance I needed and was able to keep the roof on my new purchase. As soon as I got it to the house I measured it to see what my clearance was, so I didn't have to Duck every time I came to an overpass.
