So I bought from Costco for Christmas a Quick Jack 7000TL. I have also ordered the frame extensions which will meet the lift points on the C8. I will have to build some short ramps to get some extra height for the C8, as the extensions add 1.5” to the height of the QuickJack as mother’s Grand Cherokee is to short for an extended length QuickJack. I will see how it all works when the car arrives back from Renee’s shop.
