Yesterday while leveling our 40' Phaeton, everything seemed fine. We were on a campsite, down in back and jacks were deploying, etc. All of a sudden, we heard loud noises, like gunshots, something breaking, and the 40' motorhome started bucking like teenagers' car with those hydraulics. I'm not kidding. It was violent (no alarms) and tossed us up and off our seats in the front 3 times in rapid succession. I grabbed the seat arm to steady myself and punched the on/off switch on the Atwood Level legs. That stopped it, but we were badly shaken. When it first happened, I thought I was crashing into something, but of course, we were in neutral with the air brake on. No idea what had just happened. Got out, looked around, nothing amiss, but the jacks were not all down and we weren't level. It obviously has to have something to do with them. Tenderly I turned on the Level legs again and retracted. Worked just like clockwork and nothing else happened. All retracted, no alarms, etc. Decided NOT to use them again till we can get them serviced. We started up and moved to a level site without any problems. I restarted the motorhome to make sure it aired up and popped off. No problem. When I later went to get something out of my closet in the far back, all my hanging clothes had "jumped" the rod and were tossed in the bottom of the closet. Not a big deal, but I'm telling you, this was an extremely violent bucking and I'm worried about other damage that may have occurred. Any idea what happened with those jacks?
DH checked this morning and all four mounting bolts are in position on the level legs and they show no "slippage" on the mounts. Our friend 2 sites over did not see what happened but knew we were backing in and thought we had gone too far and that we had crashed over the bank into the large deep ditch. It rained all evening, so we didn't inspect much last night but can look more today.
We have a 2006 Phaeton QSH with 350 Cat, ATwood Level legs. Bought new and tenderly cared for.
