Escape hatch replacement

Hi everyone,

New to this forum/owning a bus.

Long story short; I bought this bus the other day and already in Texas we need A/C.

I want to replace the roof escape hatch with an A/C unit but I'm having a hard time finding information on what I should get.

The hatch measures approximately 22.5" x 22.5".

Please advise,

Thanks

you need to cover the hole from the hatch with steel and have a 14" hole cut into that for the rooftop ac unit. I'm doing the same with both mine plus I'm adding two powered roof vents. Us southerners NEED AC!

Thanks for the reply. I was thinking about bolting down the hatch and just cutting the 14x14 in the hatch. Then secure the a/c to It. Those roof vents sound like a good idea

I don't know how strong yours are, but mine both leaked from the ill-fitting plastic framing and the hatches themselves were extremely brittle.
For now I have some patch panels I made from the ceilings i pulled out and they're held on by the screws that held the hatch on there.
There are also RV roof exit hatches that can be bought in various sizes too.

I've used silicone sealant for years to patch up leaks on RVs and my old van(vent hatchs seem to like to leak regardless of the type of vehicle). It's illegal to buy in California, but should be legal in Texas.(http://www.homedepot.com/p/GE-II-Win...vZc5bpZ1z115jp)

Also...can we trade places please? It has yet to get into the 60s here...

Panel over it and put a vent in its place.

The hatches seem to be designed quite well to keep rain out. You could put all the silicone you want on mine and it would still leak. Putting a rubber gasket under the knob used for opening the hatch from the outside stopped the leaking in my hatch. The hatch wasn't leaking at all. Water pools on the top of the hatch and comes through the knob hole. That caused me a lot of mopping and several months of stepping around a bucket in the center of the isle during the winter. I fixed that knob without realizing that was the source of the leak until later.

Saw a skoolie on the road once that had a snow saucer inverted over, and bolted to, the escape hatch. Simple and effective, albeit inelegant. It kept the water out and let air in.

I'm seriously thinking about doing this for my bus as an in-storage option.
