OK- - - -didn't notice the pic links before! I'd suggest raising the bed to its highest point, then supporting it with a piece of heavy pipe or some other strong prop to the ground (NOT the frame!) and checking to see how much fluid remains in the reservoir with a dipstick of some sort. If it's very low with the bed raised, add some fluid, leave the plug out, and lower the bed. If you've overfilled the tank, the excess will overflow. Don't do anything that requires you to lean over the frame without a safety device in place. A sudden failure of a hose could get deadly in an instant!
