3 Point Leveling Jacks
Just curious what everyone thinks of the 3 point leveling jacks.
I always thought they wouldn't keep the coach as stable and would still tend to rock.
What are your thoughts?
Maybe someone who has these will comment.

My Bounder has 3 point system and I've owned it since 2001. It works great and doesn't rock at all. My previous coach had 4 point and I can't tell any difference. I always put down the front first so the coach pivots off that jack and doesn't pop my windshield out or break it.

A lot of the 4-jack systems are actually 3-point systems because the two front jacks are connected together so as the rear jacks are adjusted, one front jack goes up and the other goes down. (Same principle as the ride height system)
With four separate jacks there is a big risk of twisting and popping the front windows out.

My concern with 3 jack v/s 4 jack 3-point systems (Which is what I have) is this.
The 4 jacks are all mounted to the frame rails, these are the strongest frame members on the motor home, it just does not get stronger than this..
While it is true the front jacks operate together and thus it acts like a 3-point system.. in a 3-JACK system the front jack (normally) is cnnected to a cross bar that is NOT as strong as the frame rails.

I have had a three point system on previous coach. Worked fine. Stable when deployed.

My observation is the front single is forward of the engine & when the two front are located behind the front axle you have less stress on a frame with a long wheelbase.

FWIW My Allegro Bus has four jacks, and the front jacks are NOT tied together but work independently
