We had HWH Auto-Levlers, the kick down type with springs, on a P-30 chassis. Camping world installed them in 2004. Same sort of problems after a year. Worked with them, had them repaired several times, kept them serviced. We were even stuck on them twice at different times when they would not retract. I hated them. I hated them so much that when we bought our new (2014) motorhome, I absolutely would not even consider one with auto levelers.
I bought the new RV, 4 plastic jack pads, (orange square plastic pads 14"x14"x1") and a set of 4 screw type jack stands. I have been using 2 stands when I set up. I place them under the tow hitch, one on each side. They are easy to install and work well enough. For leveling I use Lynx Leveler blocks. It all works well together and does not need oil, maintenance, or mechanics to come for expensive repairs.
On the other hand, I have read about and spoken to people who have had great luck with their levelers. For me, I will stay with the old fashioned manual way of doing things.
