Low rise lift hydraulic ideas

I was thinking the same thing about the shared hydraulic pressure source. Just isolation valves off a T? Maybe even a line in the slab off to the RV shed. That remote control would be sketchy though. My HF friend tells me a few of their hydraulic pumps come back defective so they sell them in their parts corner. Turns out the pick up tube comes out of the pump and is found at the bottom of the reservoir. That's all that is wrong with them.
