covering exterior trailer vents
We have left our 26' Fleetwood trailer on our property in John Day Oregon for the summer. We are there about every other weekend.
In our manual it suggests that when you're gone a week or more that you "cover exterior vents (water heater, furnace, air conditioner shroud, range hood, refer) to prevent insects and small animals from getting in."
Our ? is do any of you do this and what do you use ??? (ie why re-invent the wheel)...
No problems yet but at 3900 feet the insects and critters are scarce so far this spring!
Thank you in advance, Richard
