Fewer bugs and less cold air drifting in from the step. I also was trying to improve the Air conditioning figuring the cold air was dropping out thru step and into basement and down under the floor between coroplast and the floor. I think the trailer is now more consistent. I also added reflectix and a layer of pink fiberglass 4 inch thick from basement to rear bumper between the frame I beams. Sealed up the holes and coroplast to frame with gorilla tape. I stuffed the front bubble behind closet with fiberglass as well. Made a huge difference on temps in bedroom and closet.
Stilled ended up adding the second Air up in bedroom. It now cycles on and off on hot days.
Furnace runs properly and we find the fireplace does heat the place into the low 40s.
YMMV

You're Canadian, you're supposed to be used to the cold. Unless you're getting old and weak. Lol! (Just kidding!)
I've never had bugs come thru the vents, but you bring up some good ideas. I've currently got my back basement wall taken out for a couple reasons. One is because the top step HAD a very annoying squeak. The tread was rubbing on the inner wall. I ended up driving a wood wedge from the underside and cut a 1x wood brace and wedge it between the bottom side of the tread and the floor for support and I nailed it to the inner wall. I do like your idea of boxing it off and putting a 5" hole in there for the ventilation. I'd bet that would keep things warmer in the cooler temps and keep the A/C air from dropping back into there. I'm going to do that and see what happens.
I have a 2nd A/C installed in the front bedroom from the factory. Both units work pretty well in the summer. On my list of things to "repair" I started into my A/C vents and ducting. I started in the front bedroom vents and sealed up the gap between the duct and the ceiling panel. My vents have the tall ring installed on them but the stick up into the duct WAY too high so I removed them and have some better air flow. I took down the inner panels of the A/C unit to find the baffle that separates the cold air side from the warm air intake was WAY out of whack. I dont know how it was blowing cold air the way they had it in there. I installed it the right way and sealed up the cold side with heat tape. Much more air flow in there now. I have the one end of the A/C louver open and the other end closed and the 2 round vents open. It cooled the room down from 87 to 79 in 13 minutes. I'm working my way from the front to the back sealing up all the round ceiling vents and I'm going to get on the roof and remove the main A/C unit and take a look at the sealing job and the baffle to see if it needs attention. I have a little expanding foam I need to put in some areas on the underside of the trailer but first I have a plumbing company coming over in a few days to run a camera up the sewer line to the grey tank to take a peek see to see if we can figure out why it drains so slow. Black drains just fine and it's up the line from the grey and the vent is working because I opened the valve gate and used a leaf blower up the sewer pipe into the grey tank and can feel a lot of air coming up thru the vent in the roof.
