Sid: I have found a very reliable service company located in Sacramento. I had my 89 Prevost aligned there and they have an excellent front end man for rigs like ours. I recently had them do complete service on my 2000 Prevost and they were very thorough in every way. They service a lot of Fire Trucks and trucks of all sizes. They have the largest truck frame straightening device on the West Coast. Call Rick Tracy @ 916-371-6100 or Cell 916-825-7422. West Coast Frame & Collision Repair, Inc. They'r easy to find and have plenty of room for your rig. Call me if you want to discuss them.
