The Wilderness 2750RL has a cabled slideout with no underside rails or arms. To reduce the overhang stress, I've considered using some type of support beneath the slideout when left open for a length of time. However, I do not know if the slideout bottom will take the lifted pressure, even if I spread the lift over a wider area with a horizontal 2x4. Also, I do not know if the lifted pressure would unbalance the slide and its cable/pulley mechanism. Any thoughts?
