Jack,
In a nutshell, the Level Up system, made by Trailair, a Lippert company, is a 6 point leveling system for RVs. This can be done at the OEM level during the frame build-up or added on later as a retro-fit.
Retail costs for the retro-fit are in the $2,500 to $3,500 range. I do not know OEM level pricing as Heartland does not currently offer this system.
I have the system on my demo coach as a trial for Heartland. It has performed very well and I really like all aspects of it. Others will chime in with their experiences.
I see you have an '08 Bighorn. Please contact Trailair for an estimate.
