I have a cover for a 5th wheel. it will fit a 5th wheel approximately 30-33 feet in length. I used it on a 30 foot 5th wheel and it was about 3 feet longer. The opening for the passenger door is toward the rear on the right side. It has one small hole when it got snagged on the rain gutter spout. I don't know the exact length, but we can unroll it and check it out if you are interested.
