why would anyone spend $40,000 on a single lift? is the 10,000 upgrade really worth replacing it to hydraulic? I don't know the answer to that question but I do know for those of us that have already spent a hefty sum of money on a truck this is not going to happen. If you can afford to simply "upgrade" your system for $10,000 or more when it works fine the way it is, than you can probably afford to own several of these trucks. I love mine and for the first 31,000 miles between myself and the previous owner there has not been a single issue except for ordering a new remote because one of the originals motherboard had some issues. $40 fix
