Please post any pictures or give info on your shop or how you store and service equipment. To me, the most efficient system would be to have a barn on your own property, but that is hard to do with zoning, size, etc. How much rent do you pay? Can you back your trailers into the building every night? We can store our equipment in a barn w/no electric and a gravel floor. We will probably use a propane light. Will have to back the trailer in every night unless we get a covered one.
