The best one is going to be the Adco Olefin HD RV Cover item # AD54ZR. The Adco item # AD54ZR is designed for trailer's that are 23'1" - 26' long, has weighted straps that are going to buckle underneath your RV, along with cinch ropes at the front and rear to remove the excess slack. |

It's pretty likely though that this length includes the tongue, which isn't measured when determining fitment of a cover. If you take a measurement from the rear of the trailer to the front (excluding the tongue) and you get a length of between 18 and 20 feet then the Adco RV Cover # 290-64840 that you referenced will work perfectly. |
