Don’t always rely on the manufacturer’s advertised length; you’ll want to measure it yourself to get the most accurate length for the proper size cover.
You will need:
- Tape measure up to 50 feet
- Paper and pencil to write the measurements down
- A helper to hold one end of the tape measure
Measure from the front bumper to the rear of your Class B RV in the straightest line possible. Make sure to include anything that sticks out past the rear bumper like a ladder or spare tire. This is your length.
Measure the width of the RV, typically from driver side mirror around to passenger side mirror. This is your width.
Measure from the ground up to the top of the RV, excluding the height of the air conditioner. This is your height.
