I recently purchased a 2002 Mountaineer by Montana (Keystone). I have noticed that in the forward compartments i.e. Propane compartments and in the front compartment under the nose (where battery is stored), there are holes in the floor of the unit. These holes are not wear and tear holes but appear to be precut round holes around pipes and other areas. I wondered if they were for venting of battery even though it has its own vent and for the propane tanks. What I would like to do is plug the holes to prevent critters from inviting themselves in during the winter. Anyone have similar holes in their forward basement compartments? Thanks.

Put some screen over them if necessary, but don't totally enclose the area. Some venting is necessary to prevent buildup of fumes.

Holes in propane compartment are for venting propane. Mess with them at your own risk.

Put tough screen mesh to cover them. We got rats last year in there and man it was a drawn out and expensive cluster to deal with and fix. Make sure it's tough/thick with no more than like 1/4" openings... those little sob's can chew through almost anything.

X2 on using screens. My whole area under the batteries is open to the bottom of the trailer. This is there to drain off boiling out battery fluids. I always have vents to the outside above the batteries and the propane tanks from these separate compartments.I am not necessarily comfortable with the propane tanks and the batteries both in their own compartments under our 5th wheel beds above them but this is beast we have to live with I guess...This same deal follows us to our OFF-ROAD POPUP as well... When we pull out the tent bed we normally sleep in it is situated above the batteries and propane tanks mounted on the trailer tongue... We like this tent bed the best since we have a deck underneath it which keeps our four legged friends from spending the night with us hehe... Roy Ken

Propane is heavier than air. It sinks. That is why the bottom of the tank bay is open.Hydrogen is lighter than air. It rises. That is why there must be a vent in the battery compartment near the ceiling. A vented battery box with a direct hose from the top of the box to the exterior of the compartment is better.
