fiberglass roof sunken area

Hello, I am a newby. Looks like a great group. My 09 Monaco has developed a leak around the frount a/c, on inspestion I have found the whole area (about 2 ft. on each side) around the a/c is "sunken" about 1" or more allowing rain to pool and overflow thru the a/c. Has anyone had or heard of a simular problem on Monaco units?
Thanks, Jim Brown

Welcome, and I hate it for you with a water leak. I just finished tracking one down to a Skylight, that our wonderful local RV store replaced a little over a year ago. Now they are out of buisness, couldn't have happened to a nicer bunch of people.
Before going to far, if your motorhome has ducted A/C, take the inside cover off, you will find 4 or 6 bolts attaching the unit to the roof, tighten evenly, one @ a time, but don't over tighten. Good luck,

Honestly, I have never heard of this on any newer coach. If you look here, you can see the way the roof is supposed to be framed on your unit. If you have a sunken area around any of the AC units, there must be some framing missing.
Also, the fiberglass roof is tapered both ways from center out. There should be no way to achieve what you are describing. I would pull the AC off and see what is going on if it was mine.

I highly recommend you contact Monaco and get this taken care of. It should be covered by warranty if you are the original owner but get it fixed asap anyway.

Most 2009 Monaco warranties became void when Monaco went bankrupt. The new Monaco LLC did not pick up responsibility for any previously manufactured Monaco product.

Jimbrown, I know this may sound odd, but (maybe it's possible), you have the wrong size AC unit installed. If you have that much space on both sizes, something just isn't right...most of these fiberglass exterior roofs are round shaped from the center out, which helps in water run off... certainly shouldn't be flat in the center. Maybe your dealer replaced your original front AC with a smaller sized unit...
Is the AC unit directly installed centered on your roof....maybe they forgot to seal up the exterior replacement AC unit, or forgot to actually bolt the thing down all together. Can you possibly take a few pic's and post 'em for us..Might help us see your problem area. Is it exactly the same size as your rear overhead AC. Pop the outside cover off and check OK...thanks
