Jim..I've only owned two Monaco products..a Dynasty and my Executive...both manuals said:
Stop coach.
Set parking brake.
Turn off coach.
EXTEND SLIDES
Dump air
Level coach
This was the order in both manuals and the techs at Coburg.
The way it was explained to me is with their three point leveling system you'll put too much stress on the frame and may break the windshield if you level first then put out the slides.
And neither manual mentioned margaritas though they probably should have..:W....Dennis
