Hey Ron,

From what I could find the 2018 Genesis Supreme M-40GS toy hauler measures 42 feet long, and we do have a cover for that length of toy hauler, the Adco Olefin HD RV Cover for 5th Wheel Toy Haulers up to 43' Long # AD89ZR.

The # AD89ZR is an all-weather cover, so it's designed to give the best protection against rain, snow, or ever heavy sun exposure and wind. It can do this because its top layer is an Olefin HD fabric, which is an extremely durable and high-density fabric that immediately beads water and repels dirt particles from penetrating the cover.

Hey Ron, how did the Adco Olefin HD cover end up fitting your Genesis Supreme toy hauler? Your update could make it easier for the next person looking for a cover that size.
