So, if it should be level then how does it operate the same while going down the road? I think a lot of this is conjecture. Works fine on either while travelling I would think it would work fine if it wasn't 100% level parked. I don't know if it's over thinking or what but I think a lot of folks on this forum borrow trouble.
Below is the type of information people can get if they would just READ their operation manuals.

Operating refrigerator outside of the cooling system specifications of 3 degrees off level side-to-side and 6
degrees off level front-to-back can cause irreparable damage to cooling system and can create a risk for personal
injury or property damage. Level vehicle before operating refrigerator
Absorption cooling system.
In an absorption refrigerator system, ammonia is liquefied in
the finned condenser coil at the top rear of the refrigerator.
The liquid ammonia then flows into the evaporator (inside the
freezer section) and is exposed to a circulating flow of hydrogen
gas, which causes the ammonia to evaporate, creating a
cold condition in the freezer.
When starting this refrigerator for the very first
time, the cooling cycle may require up to four
hours of running time before the cooling unit is
fully operational.
The tubing in the evaporator section is specifically sloped to
provide a continuous movement of liquid ammonia, flowing
downward by gravity through this section.
Sodium chromate is used for corrosion protection (less than
2 weight % of the coolant).
Leveling the refrigerator.
Leveling is one of the requirements for proper operation with
absorption refrigerators. to ensure proper leveling the vehicle
needs to be leveled only so it is comfortable to live in (no noticeable
sloping of floor or walls).
Any time the vehicle is parked for several hours with the refrigerator
operating, the vehicle should be leveled to prevent this
loss of cooling.
If the refrigerator is operated when it is not level and the
vehicle is not moving, liquid ammonia will accumulate in sections
of the evaporator tubing. This will slow the circulation
of hydrogen and ammonia gas, or in severe cases, completely
block it, resulting in a loss of cooling.
When the vehicle is moving, the leveling is not critical, as the
rolling and pitching movement of the vehicle will pass to either
side of level, keeping the liquid ammonia from accumulating in
the evaporator tubing.
