Why not just buy and install a mud dauber screen over the vent opening/ Did that to my Suburban furnace, Dometic refrigerator vents, Suburban water heater and the A/C roof top unit. The rubber end caps on the bumper are a favorite entry point for wasps, so I cut some aluminum window screen and hot glued it to the inside of each cap. Wasps and spiders can be a real problem and seem to favor RV's. Only had our new trailer one month and sparrows were entering the roof top A/C and building nests back in the squirrel cage blower.

Happy camping to you......
