Should I leave it on or off when connected to power for an extended time? Thanks.
Dometic suggets leveling so that it's comfortable to live.
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."
As for the disconnect, leave it on so the batteries can charge. This assumes you have a three-stage charger with your converter. Almost all newer trailers will, but check your manual. It's all there.
