Is this the right engine?  If so, then "...in drive with AC on 750-800 RPM".

Set it as low as possible while still remaining smooth. That likely will be right around 700rpm. On my coach, I had to bump it up after buying it as it rattled everything inside at idle in gear. Using a photo tach I was right around 700-725, if I remember correctly.
