ATEL

ATEL is a heavy-duty collision, body and diesel repair shop based in Beltsville, Maryland, at 12120 Conway Rd, close to I-95 and the Baltimore-Washington Parkway. It works out of its own 40,000 square foot facility, so you bring the RV to the shop rather than them coming to you.

On the RV side, ATEL says "ATEL handles collision repair, body work, full refinish, custom paint, decal restoration and chassis service in a facility built for coach-length vehicles." It also does dedicated roof work on Class A motorhomes and diesel pushers: leak diagnosis, panel replacement, reseal, and removal and resealing of AC units, antennas and vents, on aluminum, fiberglass, TPO, EPDM and composite roofs. It works on Class A, B, C and Super C motorhomes, diesel pushers and full-size coaches up to 45 feet, with a 45-foot and a 65-foot heated paint booth for full-coach refinish and a 40-foot frame machine for chassis and structural work. Its service area is the DMV, meaning Washington DC, Maryland and Virginia.

No trip fee, hourly rate or diagnostic fee is published, so ask about cost and scheduling when you call. Hours are Monday through Friday, 7am to 5pm. ATEL also coordinates aftertreatment warranty claims with OEM and extended warranty providers, with diagnostics documented and parts traceable, which matters if a diesel pusher's emissions system work needs to go through a warranty claim rather than out of pocket.

ATEL is family-owned since 1994, so roof and frame repair on coach-length vehicles has been daily work there for more than three decades. Google rates it 4.2 stars from 84 reviews.

This is a good fit for an owner of a Class A or diesel pusher coach who needs a roof leak traced and fixed properly, collision or frame damage repaired, or a full repaint, and who can get the rig to a shop in the DC, Maryland or Northern Virginia area.
