I'm having trouble with two systems in our fifth-wheel. We have two slides in the living area (connected) and a bedroom slide. We also have Lippert leveling jacks. The functioning bedroom slide is...

My first thought is your tech is clueless, find someone experienced. Rack and pinion suggests electric. Hydraulic would have 2 hoses per cylinder - 2 for a jack and 2 for each hydraulic ram. He should be able to easily determine what you have.
The thunks are likely a solenoid or heavy relay. Your switches cannot handle the very power draw so they activate the solenoid which has a second heavy wire from the battery.
I would start with a digital voltmeter connected to a clean frame ground (not a wire) to the battery + cable. What is the voltage when the clunk occurs? Continue downstream and you should have close to 0V on the negative wire and 11-12V on the positive wire to the motor.
I'm also wondering if the batteries are wired correctly, one or more reversed. And don't assume new batteries haven't failed, it happens.
