slde out air

i have always known this, but some reason became more curious today.  when the slide is out, there is some obvious light/air/breach coming in along the bottom where the rubber flaps are.  no major concern but am assuming heat and cold!!!!! inside air are lost.  anyone do anything to rectify this?  hogone

We have noticed the same issue with our 177 - I don't know that the air flow is a big deal although - I believe in the fall we have had mice come in thru this gap and when camping in peak mosquito season I am pretty sure they are entering thru that gap as well.

We bring blue painters tape and tape the gasket shut along that bottom edge when we are camping in really buggy spots, or in the fall when mice are looking for a warm place to sleep.
