It really depends a lot on the type of jacks you have. I have the HWH series 200 kick down jacks and have rolled forward several times. One time I pulled into a campground after dark and could not tell how unlevel the site was and rolled backwards and jamed the rams into the dirt and grass and they would not fully retract until I cleaned and lubed them. It is quite scary when a 16,000 lb MH rolls of the jacks. They ARE designed to roll off with no damage.

They are NOT designed to roll off with no damage. Granted, you may not experiance damage, but they are not designed to do that. Kick Down HWH jacks are designed to gently drive FORWARD to drive off. IF the Motorhome moves rearward, you will destroy the jacks if they go to far. They are NOT designed to roll backwards. They will lock and break or damage something. Doug

Not according to HWH when this happened to me I called them and they told me they were designed to roll backwards and forwards and not fail. I spent quite a bit of time with their tech on getting the pistons cleaned and working again. That was 6 years ago nothing broke and they still work fine. I know you disagree with silicone spray but he told me to clean them with silicone spray or WD 40 with I use once a year to keep them retracting quickly.

You misunderstood what they told you. You CANNOT roll backwards or drive backwards with Kick Down jacks. THERE IS NO PIVOT TO ALLOW THAT GOING BACKWARDS. It will damage the jacks and mounts. Doug(working on HWH for 30 years and HWH factory trained).
