need model number on jacks
I suspect they are hydraulic, a pumps supplies pressure
a 12v electric valve controls the flow for each jack
the switches connect to a control board, that controls the valves
did you hear the pump running ? or did it stop running
if running, could be low on ATF fluid, or bad connections or control
if not running, its the most costly 'problem' in the list
you like the 'floor plan' design etc
i think i would look for another RV with a similar floor plan
at least consider the fact, you could spend thousands more if you have to replace the jack system
and instead end up using portable plastic leveling blocks under the wheels, about $30 per set, one set for each wheel
for this system this age
it might be 'manual mode' to get each jack on the ground
and 'then auto level'
i prefer manual mode all the time, i don't like the way auto level works on most systems
getting the rv higher than necessary
