Camper height

The camper dimension calculation

For the height, width, and length calculation, you have to check that information from the RV manual or some of its manufacturer’s official websites.

If you have two equal options of tunnel and bridge, then prefer the second one. If it is impossible, then make the complete inspection before entering.
