If you have a welder we made a fold down walk way with steps at the back, it took a few attempts but it folds to be set out by 2 inches when travelling. It is suported by a simple sliding tube. The difficult part was to make the side rail carry the suport chain for the steps and transfer the strain across the rail and back to the support bar. It took a good day to do but is very simple with just two legnths of piano hinge 1x2 & 1x1 box and some 3mm chequer plate.
