Duct Heated Underbelly

I have just purchased a Shasta Flyte 185FQ. It does not have a ducted furnace but since I will be going up north while it is still dropping below freezing every night I am having the dealer add the "heated underbelly". I have a few concerns. I will be staying in the middle of a National Park. I DO NOT do little critters. My preference would be to bring the unit home, crawl around inside and outside sealing EVERY crack and crevice. This is not going to happen. I have asked the dealer to seal everything but my biggest concern is if there is a small duct running from the furnace that is left open in the underbelly to heat it, will mice who do find their way into my underbelly be able to enter my unit through the furnace? I searched all the posts about duct heated underbellies but can't find out if this is a possibility. I was hoping they used the electric pads but they don't.

If a mouse did get into a heating duct it would definitely be able to get into the trailer. In addition to sealing all openings, use repellents such as dryer sheets or peppermint oil.

Put screen over the end of the duct? Should keep any lurking critters out. I went as far as taping over the heater exhaust, fridge vent, and WH cover when I winterized. No so much for mice, but more for those damn stinkbugs!
