Lippert introduces new leveling system for RVs
(Aug. 8, 2012) -- "Ground Control is available in four and six point OEM configurations and in a four-point aftermarket version. All versions are up to four times faster than any other electric jack systems – leveling in just three to four minutes – and have a 5,000-pound per jack rating with an automatic jacking feature. Ground Control is an add-on that any RV owner would like to have.”
