Hey Doug - You can try Ferguson Automotive Equipment in Baltimore City, phone: (410) 467-8980. The father/son team team that installed my lift works for them and did the job on the side. Lee's right, they did a good job but never returned my calls after the job, so I wouldn't recommend them. However that's what the company does, so if you go through the company, you would have a better chance of getting follow up service if you needed it. You can also try Beltway Lift & Equipment out of Middle River, MD, phone: (410) 335-2922. I've used him for some service, was satisfied, and will use him to do all the maintenance that I may need in the future. If you want I can call him and see if he will go to Mt. Airy.
