I went with the same existing levelling jacks.
Went old school, non proprietary hydraulic pump with 5 manual levers.
I do it all from outside in the same bay as sewer stuff.
I bought a wifi enabled unit thats mounted in coach that tells my phone when and where I am close to level or not.
Great for boondocking.
Then when I am in good spot, stop go outside activate all levers, while hearing what's going on.
Heavy duty pump was used from dump box, with dual action levers.
I can go to any industrial supply house to replace any parts.
No calling an rv dealer that has no clue anyhow.
I like non proprietary elements, KISS formula.
Not for the average Joe, but I know stuff and love to make things work my way.
