How about these to put over the LP gas vent holes from underneath to keep water, etc. from getting into the compartment while driving?

Good idea.

I had tried these (same thing different make etc) and the heavy rain still came in. You need one that has "fins" about 3/4 to 1" long or they will NOT stop it. Believe it BTDT
