Passport AC Duct Work

Hello,

I have a 19 Passport 2400BH that we absolutelt love, but we're having some AC air flow issues. There are 4 ac vents in the camper, 2 in the back and 2 in the front. The 2 back vents blow hard and great it's the 2 front that trickle and don't really help. This isn't really an issue as the unit keeps the whole camper cool all day and we actually froze in Gatlinburg during 90+ days in the direct sun. However I'd like the two front vents working better as at night our bedroom gets a little hot when we slide the doors closed.
So I took off the AC inside cover to check for leaks and gaps between the return and blow sections and actually noticed that the duct to the front vents doesn't connect directly to the AC at all - there is a pretty sizeable gap it seems. I was able to reach in and touch the roof insulation as well, leading me to believe I'm pumping most of the cool AC air directly into the ceiling instead of the camper itself. The back ducts however look like a solid connection with no gaps.
My question is, what can I make to put up there to guide the air into the duct? I was thinking of just cutting some aluminum the width and height needed to block off that gap, but wanted to see if anyone has had any experience.
Thanks!!

Probably one of the easiest materials to work with would be coroplast. You can buy a "for sale" sign at WalMart, Lowe's or Home Depot for about $2. Cut it down to fit the area properly and use aluminum DUCT tape (not the cheap DUCK tape with fabric backing) to secure it in place and seal the area.

Thanks for the reply, it looks like we have the same issue.
What material did you use to route to the duct? Aluminum duct tape?

Thanks this helps and is definitely along the lines of what I was thinking of using...

This is where harbor freight comes in handy
