AC removal

[okgypsy]

Anyone have advice on removing roof top ac? I'm not going to use it.
Any and all help would be appreciated. Sealing it for leaks, what you used,
How did you cover it? What materials and tools, etc... thanks!

Not too hard to remove, assuming you have access to the roof. It is connected through a standard, 14" roof vent opening. I replaced mine with a Fantastic Fan, which fit in the same opening.

The procedure is to disconnect shore power,
remove the inside cover,
remove the four long bolts,
disconnect the bottom plate and remove,
using a putty knife work it around the top skin and the AC unit,
once the adhesive released the unit can be lifted from the top,
my unit is kinda bulky, you will like need help lifting it down perhaps covering the skin with something to protect it, in my case I used a forklift and slid the unit onto the forks, I know that is cheating but the trailer already has enough dings on it.

Your older AC may be sitting on a plastic saddle that accounts for the curvature of the roof. If so the unit should may be sealed directly to that form. I would break any seal there and lift the unit off and then work the plastic saddle off the roof.

Also you may find that once you remove the ceiling cover, the hold down bolts, and the supporting metal bar that the unit is sealed with a heavy compound on the inside directly at the roof line. That is a bear to remove but has to be done. Just be careful as there is sharp metal edges there.

My '67 GT had 2 factory vents with a center mounted Coleman A/C. I checked some spec sheets for those years couldn't confirm any A/C prep.
Depending on how the unit was installed you may have a decent 14x14 opening in the roof. It was common to add 2x2 wood braces for support.
A Fantastic Fan is a good choice to replace the A/C if the opening is OK. You may need to run 12 volt wiring for the fan from the other roof vent fan. If not there are on-line suppliers of the Alclad Aluminum 2024 0.32 sheet to patch the roof with Tempro sealer and Olympic rivets.
The inside skin will be much more difficult to match.
I've used On-Line Metals for a number of projects with good results.

Good Luck.

I removed the ac in a lance camper we once owned and found a 14 x 14 opening between upper and lower units and filled the space with a fantastic fan. We liked the skylight and better ventillation it provided since we never camped with hookups and running a generator so we could run the ac was not in the cards either.
Now you got me thinking about our Airstream...same camping profile, except it will be set up as guest quarters when at home.
