Back in 2014, I had my driveway expanded with 4" thick concrete, including a fairly wide pad next to my one-car garage. Initially the pad was supposed to be for a place to keep my trailer when it's not in use, but I've been winding up using my trailer way more often than I thought so it doesn't make sense to move stuff around to badly back the trailer in just to take it back out for the following weekend. The trailer lives on the side of the street behind the truck.
We have an autocross club that uses the local minor league ballpark, and contract with that club to keep its equipment van since we live closest to the site, have the space, and have two drivers so we can get the van there while also getting our car there.
But said autocross club hasn't hosted an event in two years, and an informal poll of the powers that be in that club shows only tepid interest in putting something on down the road (the local site has unresolved issues with nearby neighborhoods and won't schedule anything until those are dealt with, whenever that might happen). In light of this, there's the possibility that the club may fold, and if that happens, the van goes away.
This would leave me with a decent-size concrete pad next to the garage that isn't great for parking cars (whatever winds up there will get blocked in by whatever's in the main driveway). At some point I got the thought that maybe it could be used for a two-post lift.
I don't remember the PSI of the concrete used, but last I looked, it meets the specifications I found somewhere online for being able to have a lift on it. I'll have to dig up the paperwork from the concrete contractor to be sure.
The biggest question mark is about how weather-proof these lifts are. I've seen outside lifts on car-building reality shows, but they're usually in southern California. We're not there, we're just south of Washington DC where we get rain and snow and cold. I don't know if they make lifts that can shrug stuff like that off or if they're all designed to just be used inside or in very dry environments.
As an aside, I wonder if I really need a two-post lift. While my garage isn't big enough to work on stuff inside it (it *might* if I clean it out like I've been meaning to, but even empty it's kinda tight), I have a Quickjack and do a lot of my own work in the driveway just outside the garage door. I don't need the lift, but I think it would come in handy at times, assuming it doesn't get all rusty from being outside.
I'm curious how the members of a forum that makes/enables a lot of dumb ideas think about what could be just another dumb idea.
