I looked at using a 12 v linear actuator but many of my attachments require a lot of force to activate the latches. I have decided to use a 12v hydraulic pump and a hydraulic cylinder. I can get the pump for $200 and cylinder for $79 and hoses for $60 for total of approx $350.I plan to mount the pump in the right rear engine compartment near the crankshaft. Going to run switch into the panel in cab. Please help me with any problems that I have overlooked and reasons nobody has tried this before. TIA
