Call around to find names of lift installers/service companies. They visit local independant and franchise auto repair shops. These guys install and remove lifts all the time and will be able to put you on a waiting list.
I actualy got my lift, a 9000lb Bendpak asymetric, off of Craigslist for $1600. A GM dealer went out of business and had a couple to sell. You’ll see alot of that recently I’m sure. I would recommend the 2 post over a 4 post, and the asymmetric is nice if you can find that option as well.
It cost me around $300 for him to install it including the large anchors, and I highly recommend doing that.They will do in a few hours what it would take you three days to do. Positioning of the 2 posts is exact, and they are extremely heavy. I know because I had to load mine on my trailer by myself with an engine hoist. You will need a 110V circuit for power, and spec on he concrete is actually 4.25" depth and I think 4000psi. You can go to their website and download stuff from the FAQ section. You don’t want to play around lifting that crew cab truck.
If the house isnt built yet, put a drain in the floor under where you want the lift, then you can use a pressure washer in there to clean the underside. Billy Gropp has that and its really nice. I still have to go out in the driveway and use jackstands if I want to wash a car on the underside.
