In our '13 3010, the lower bench seats of the Happi-Jak system have (4) fold out supports under the benches that I suppose should contact the garage floor when in use? This weekend we had guests stay over for the first time and thought we would give the garage bed a try. After pivoting the support arms down and lowering the bunk to the bottom position, the supports were still almost 2" away from contacting the floor? Are the supports the wrong length or is the limit switches incorrectly set? I'm not sure if there is enough stroke left in the Happi-Jak tracks to account for this discrepancy. Does everyone else use the center braces?
