[first time 5er]

After further inspection i have come to the conclusion that it is not a vent. The hole is for the propane lines but i think it was cut in the wrong place. Go figure? the vent tube that i see is part of the "polar Package" to keep the tanks from freezing. They just happened to be in the same place. I'll just cover the hole with some 1/4 " box mesh and foam it up.
