I have selected at totally random just ONE of thousands of window AC manuals that CLEARLY point out for correct installation to slightly lean the AC off level.
PLEASE NOTICE the manufacturer IS indicating 1/4" drop!
On a camper, virtually the entire unit is inside, so the illustration simply doesn't apply. On a camper the water is going onto the pan, regardless of how the A/C is tilted. In my experience, the pan extends to the inside beyond any openings on the bottom of the A/C. Any inside leak is much more likely due to the pan than the unit itself. The A/C could be mounted at an upward angle and still end up draining well with a proper drain pan.
