garage stall/bay rentals near Riverside?

[tetrad]

Does anyone know of any rent-a-bay type places in the Inland Empire? Ideally as close to Riverside as possible.

I just got my hands on an 88 Comanche that needs some love, but I'm unable to do any serious work on it at home. I'd settle for a storage unit place that didn't mind me actively working on a Jeep on jackstands with an axle out (in some ways that might even be preferable to an hourly bay/stall rental).
