New roof a/c unit

I searched the forums and couldn't find what I was looking for. I'm looking to replace the front AC in my 94 Winnebago. It's non ducted. I can get a new Coleman 15000 btu for $650.00 from Redneck. Its the top unit, the inside ceiling assembly, and the heat strip.

My question is, should it come with a new gasket to seal the 14 x 14 opening, and has anyone done this themselves?

I'm very handy, and also can pass the new unit out my daughters bedroom window right on the the roof of the RV.

I've cleaned the coils in the old one and it just doesn't put out enough cold air. It's 20 years old and it's time has come.

Thanks in advance for the help folks.

    Thanks guys. What about the swap. Looks pretty easy. I'm figuring that getting the A/C's on and off of the roof is going to be my hardest part of the job.
    Will the roof on your Winnebago safely support you and the a/c's weight at the same time? If you're not sure, might want to protect the roof with some plywood while you're walking around up there.
  • Ya, the worst part is lifting its 100# weight up on top of the roof.
  • Swap is easy but I suggest at least two strong folks to do it just for safety.

    Make sure when you tighten down the hold down bolts you crush the gasket for a good seal. I tightened mine down to where the A/C unit felt secure (wouldn't move). First rain I had leaks...retightened to where I could see the gasket crush and leaks went away.

  • Yes, it should come with a new gasket. If I remember correctly, there is adhesive on one side to keep it in place while you work. You pull the paper backing off and set it down around the opening.
