How to add Coleman rooftop AC to '72 Argosy 20

[airfoil]

I recently acquired a '72 Argosy 20. Some of you may remember the camo paint job which, by the way, I am in the process of redoing. I also reciently acquired a used Coleman 15,000 btu roof top ac unit. The Argosy does not currently have an AC unit.

I want get any advice as to how I should go about installing this unit. Looking at the breaker box, it appears that it is set up for 20 amps. Is this suitable?

Also, I noticed a thread including comments by Andy at Inland RV reccomending against installing in place of an existing vent. Where should the ac unit be located?

I have a zillion questions and after having studied this forum a great deal, I'm sure many un-asked questions will be answered for me. The collection of experience here on this forum is very impressive.

Thanks,

John
