Roof AC Replacement - Help needed

[roadwalt]

I just lost the front AC (Penguin) on my 03 Kountry Star. Has anyone replaced one ? I am interested on how to unbolt it from the roof. Can you gain access by removing the Florescent light ? My new replacement is being shipped to my son in CT, and I will be there in a week or so, Just trying to get a handle on how to go about it... The install sheets that came with the one in the rig says to place unit over hole in roof and center etc, and bolt it from inside the coach.. Of course nothing protrudes below the ceiling so there must be some way to make sure the air boxes line up properly and bolt it down from inside...
Any help would be greatly appreciated....

Your biggest challenge will be getting the old one down and the new on up on the roof. Based on you post I'm assuming you don't have ducts in the ceiling. My units are bolt from above the roof so I don't think I'll be much help but if you have enough muscle power the replacement shouldn't be too bad.

Ours bolts from the inside. Cut the roof gasket from inside, thru the inside opening. We pushed the new one up onto the roof in it's shipping box on to the roof. Used many blankets to protect the roof. We apply lap sealant to the new gasket to provide an extra water barrier. The reroof link below shows pictures of the a/c unit off the roof & it's underside. Happy to answer any questions.

Your AC has four bolts from the top side on roof. ALL wiring and bolts will be from top side.
You will have to be careful of the AC seal to your ceiling ducts and not tear them. Click the arrows.
I have Duo-Therm AC's on my 03 KS HERE IS A PDF.
There is more information in the Quick Tips Link.

Thanks everyone for your input... I had to put the cover back on after determining that the compressor had seized up... I did see some pretty large (I thought nuts) on the perimiter of the unit... I didn't know if the air box would stay and the new unit would sit on it.... I will study the pdf's and see if I can determine that until I see the new units bottom side and can get up there again to look deeper into how the old unit can be removed.
It will be at least a week before that will happen, I will keep everyone informed of my progress.
Again a great group of guys with help when you need it. Thanks.
