My 2607 was similar in design. The under bed plywood was screwed down, and there were two small drawers installed under the bed, one from each side.
I unscrewed the plywood, installed a long piano hinge. I then uninstalled the drawer systems, unscrewed the drawer-face from the drawers, installed hinges and a magnetic catch, and made them access doors.
After attempting to find a proper size/strength gas strut with the right monting brackets, I gave-up and made a prop-rod out of an old broomstick, with a "socket" for it on the underside of the plywood made out of a screw-on door bumper.
I now have the entire under-bunk area, where we store extra bedding - an extra quilt, extra sheets, two comforters, extra pillows, a step stool, the "spare" globes for the awning lights (red, white, & blue for holidays), and a couple of games.
Much better use of the space! Anyone want/need any drawer hardware?
BTW - Total job cost, less than $30, with the piano hinge being the most expensive part.
