I just reviewed the attached drawing and you were just perfectly right with your understanding of our hydraulic cylinder's specification (RVL std) as shown in the details provided. However, please consider having the rear end of setting number 1 tilt higher than the front end. Meaning to say, the rear hydraulic cylinders must extend higher than the maximum length the front hydraulic cylinder could extend.
Just to give you some inputs for your design consideration, when our hydraulic cylinder number 1 mounted at front end is fully extended, it can raise up setting 1 flooring up to a maximum of 1430 mm high from 5th wheel floor line to setting number front end part floor line while the hydraulic cylinder mounted at the rear end part can raise setting 1 flooring up to a maximum of 1960 from 5th wheel floor line to setting number 1 rear end part floor line.
This is just to give you an idea but as I already mentioned, the 5th wheel head room consideration provided to the prototype was already enough. If this can be maintained while attaining 2100 mm l level for setting number 1 ground to setting 1 floor line or even lower if possible then our objective is achieved.
Best regards.
