Result:

If you look at the attached map you'll see that it is listed as being rated for the northern and central region of the states. This cover has zippered panels on the passenger's side and rear offer easy access to storage areas. |

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. |
