    Hi All,

    I have a '99 Jayco Heritage Laurel with A/C (I think it is a Coleman Mach 3). The A/C unit is raised on one side in the rear corner which appears to be causing the roof to lean in the opposite direction. The hole is off center(Factory Cut-Out). Will longer bolts into the A/C unit help grab the threads and tighten it down onto the roof? Sorry about the lack of detail, this is the best way I can describe the issue. Please feel free to ask any questions. Any advice would be appreciated.

    Are you saying the corner with the A/C is Higher than the opposite corner?
    Is the A/C loose? If not, different screws make a difference.

    Take the A/C unit off or moved out of the way and install a new gasket , should be replaced every 6 or 7 years especially if it's stored outside

    The A/C is in the center of the roof from front to back but is closer to the road side. The roof leans to the road side. It was tight, would longer screws help bring it into alignment?

    If what I'm reading is what you're trying to ask, no. Is the roof the same height on each side, measured from the top of the box to the bottom of the roof side board? Are you sure the trailer is correctly leveled?

    The trailer is level. The lifter arms are slightly bending towards the road side. The hole is from the factory. The roof is internally braced based on other jayco's of the same year that I have seen with A/C. I am just perplexed as to why my roof is leaning.

    Sounds like it may be more of adjustment issue with the cables.
    And I need to edit my first reply. I left out the word "wont". If it is right, longer screws wont fix anything.

    My AC is also placed to the road side, I'd say 3/4 to 1/4 of the roof to the centerline of the AC. Moving it around couldn't affect the roof balance. Either the pup is not level or the roof is not level on the pup.

    How do I adjust the cables and fix the tension?

    Colemans are different and I wouldn't want to lead you wrong. Search through the Lift systems section for "whiffle tree." Or maybe one of the Fleetwood/Coleman guys will come to help out.

    Not sure about your pup, but i would look to see if anything is loose at the top of the lift arms, where it connects to the roof. They should have play in them but nothing like leaning.

    I found the problem. The front curbside lift arm was loos . Turns out the top plate that attaches the lift arm to the roof came unglued/unepoxyed. Now to secure it

    The image below is the plate that sits on top of the arm and attaches the bolt assembly to the roof. https://photos.app.goo.gl/ppwpbx4rHCd2SRrY7

    Gorilla Glue worked great.
