Electric stabilizers unleveling trailer

I had another shakedown trip last week in our new Lacrosse 301RLS and wasn't happy with the stabilizers. I haven't had electric jacks before and what I found was that after I parked the trailer so it was level, I'd drop the jacks and then the trailer was very off-level.

This trailer has Lippert jacks with a single motor driving one "screw rod" connected to both jacks. I'd asked the tech during the PDI if jacks were "self-levelling" and he said "sort of". Well I crawled underneath and looked at the mechanism and I'd say that both jacks move the same - there's no differential that transfers the motion to the other when one stops. I conclude that you must ensure both jacks touch down at the same time or the suspension will move on the side that touches down first and tilt the trailer.

Is there a trick to getting around this or must I carry a selection of "shims" to compensate for uneven ground? (The parks I visit rarely have level concrete pads).

My rear stabs self level.

Put them half way down then grab one and push it down.
It should go down and the other should go up.

I have a 318bhs and I'm pretty sure I have the same jacks as you do. Mine will self level. Once the first side touches its pad it will stop moving until the other side touched down and they load up together.

They are self leveling, I would check to see that they are not bound up at the top. The motor should go in and out to be able to self level. Suggest lubing the rail the motor & screw are in.

That's great news - assuming I can find out why mine don't appear to .

We're going away for another (and, hopefully, final) shakedown trip next week and I'll check this out more thoroughly.

Thanks
Bob
