I had Bigfoot leveller on my Newmar Mountainaire 40 foot fifth wheel. They were flawless for 12 years.
The current owner just told me they still work flawlessly after 20 years. It was a 4 point hydraulic system. They stabilized muck better than my Lippert 6 point system on my 2018 DRV Elite Suite.
I toured New Horizons Majestic Fifthwheel plant a few years ago and they were still using the Bigfoot system
I highly recommend aftermarket Bigfoot
