Looking for some Hydraulic Help

I am building a large tool box on a Ford f350. It will be 4ft tall & 8ft long & 2 ft deep. A 4ft x 8ft side will be one large door tied into the 2ft x 8ft top panel so as to open like a gullwing. This door will be in aluminum & weight should not exceed about 75lbs

What i am looking to do is to try & set this up to open & close automatically. I figured that a hydraulic system would probably be best. Weight at the lifting points on the door shouldn't be more than about 150-200lbs Problem here is I really don't know jack about hydraulics. I have been researching it some on the internet & have found pieces & parts but not much in the way of "How to" I called a couple people but I felt that they were selling me on something excessive (probably liability issues there)

So the question here is: Is there a real simple way for me to set this up. Maybe 2 ramms per door, one 12v pump/motor and a 12v switch to actuate the doors? (Vendors are wanting me to have a resevoir, expensive pumps & this & that to get the price to around $700. I am a boater & my hydraulic tilt / trim motor only cost around $100 & the switch for it seems to be nothing really special.) For my toolbox here I can get ramms for around $30ea Seems to me that just a simple pump should be it for me not a $300 one + a resivior.

I have seen pumps online (Like at Great Plains catalog) but there are no specifics as to a motor for them.
