I've got an electric hoist too. They're useful and cheap but you need somewhere stable and high to mount them too. That's a much bigger challenge / problem than it sounds. You're not going to be able to mount them on drywall. you'd need bars or a gantry higher than your cab and strong enough to support a 100-300lb crt plus 30-50lb for the hoist itself.
Before I got my shop crane, I tried to use one to lift a cnc machine onto a desk. The aluminum T-slot gantry frame I tried to construct for it was an incredibly time-consuming and dangerous failure....
