The shop
Meet David.
David HarkinsOwner · Seven Heavens Mechanic
David runs the shop the way a good foreman runs a floor: show up when you said, do the job once, leave an itemized bill. The crane-equipped rig means an engine swap in your driveway, a machine repaired on the job site or an inboard lifted out on the trailer is a normal Tuesday, with no shuttling your vehicle across town and no shop backlog.
Heavy equipment and large vehicles, automotive, inboard marine and vinyl wraps: wrenching, lifting and the finish work. If it broke where it sits, that's where we fix it. When a motor has to come out, the crane on the back lifts it onto the bed, and the replacement goes in the same way.
