Do you mean stability when driving or when camping?
Driving: Most motor homes have leaf springs all the way around these allow the body to shift not only up and down (As you would expect) but side to side a bit as well. The addition of Track Bars (I added one on the front, I'm told rear is more effective, two are best) stop this "Shifting"
Good shocks handle side to side Rocking
And a good sterring stablizer. I went with Blue Ox due to the "Remote adjustment" button in the cockpit (next to the driver)
But Saft-T-Steer now has that as, last I knew, an option so it too would be worthy of consideration.
How much difference do these modifications make?
Before Mod I towed my car from Detroit to Las Vegas
It was a relief to park the house and drive the car
Then I added the front trac bar and stablizer
And again towed the SAME car to las Vegas
And it was amazing how much harder that car was to drive
(I'd gotten used to driving the stabilized motor home)
I can explain why but that is a longer post.
Home was where I park it. but alas the.
