Dometic inside vents

[hilloah]

I recently had the FEMA Cherokee 28A+ changed to a new Dometic. Since I have never used the old one, there was a bunch of stuff in the vents. I took it out. When winter comes, am I supposed to have stuff to "close" this AC vent? Thanks for your advice.

Which vent are you talking about?
In any case, I've never heard of anyone 'closing' and A/C vent either intake or return.

There are 3 circular vents that have slits for changing the blow of the cold air. I got a DVD about the intake vent and cleaning the "filter" and I do not mean that one. What I want to know concerns keeping the Cherokee warm during the winter. Will the warm air leak out those circular vents if they are not blocked in the winter time?

Does that make it clear? Thank you.

That makes it perfectly clear.

I don't know where you normally camp, but if it's in really cold weather then it may be worth blocking off the ceiling registers, though I've never heard of anybody needing to do that.

The ducts are somewhat insulated so even if warm air rises into them it won't readily escape out into the atmosphere.
