I love my Lippert 3.0 Ground Control system. It makes it very easy and quicker to set up. One down side is you have to be careful backing over curbs and other things like stumps with the back of the camper. There is only 7"-8" clearance above the ground on some campers. I did not install mine, got the Montana High Country 305RL with them already installed.
One thing - be sure you don't need the 6 point system. Lippert has a chart that determines the max distance between the rear jacks and the wheels. I think you will be right on the edge. Etrailer says OK for 4 point, but you may want to check.
