What does your waste valve look like? Does it look like this? If so, mine is just a small sturdy strip of metal drilled with a hole to fit over the vavle pin. The metal strip is attached to a T-handle. You insert it through the hole in the rear bumper, fit the handle hole over the valve pin, turn counterclockwise, and pull. I can't get a picture of mine until next week sometime, but it looks like something that could be easily made. I was using a channel lock directly on the valve pull until I found the handle in a box under one of the twins.
