Locowrench,
I could be wrong, but I believe Lippert bought the rights to the Ground Control leveling system from Rieco-Titan at the same time they bought the Correct-Trac alignment system from them.
Lippert markets the Ground Control 3.0 system as either a 4 point or a 6 point leveling system and it looks exactly like the Rieco-Titan system. BTW, the Ground Control system is no longer on the Rieco-Titan website, although they still do have the flyer and the install instructions available if you dig deep into their webpages.
Although it doesn't look like it would be difficult to install, I don't think I'd want to tackle all the routing, drilling, installing and aligning that goes along with the installation. After reading the instructions, it seems that someone with the right tools, time and mechanical aptitude could get it installed and working. It wouldn't be a "dealer only" installation, from what I can see.
But, the $3000 price tag for the parts only would be a major consideration for me. I don't think you'd ever get much of that investment back at trade in time, so unless it's a relatively new RV that you're planning to keep for a long time to come, the investment probably wouldn't pay for itself.
Here's the Rieco Titan installation page:

The Ground Control system is the fifth one down.
