can you post photos of the jack used to lower Onan generator from Roadtrek 190? I had the same idea, but have not yet "made" the attachment. I measured the bottom of the generator plus 2" on each side and drawn that onto plywood to make a "tray". I had the idea of attaching a 4X4X2 piece to the bottom side of the "tray" and use a hole saw to drill a hole in the 4X4X2 into which the jack lift point or head would fit. I imagine the gen could still get off balance and tilt unless someone assists: one holding/balancing the Onan and one lowering the jack.
