Gander RV, formerly known as Camping World, likely sustained millions of dollars in damage after a fire engulfed the large commercial building and vehicles in Antioch, officials said.

The Antioch Fire Department responded around 7:30 p.m. Saturday to Gander RV, 41517 Route 45 in unincorporated Antioch.

Firefighters arrived to find heavy flames and smoke coming from the roof of the building, which is an RV service center.

Crews had to force entry through a locked gate to gain access to the property, the fire department said.

Firefighters faced heavy fire and explosions from a north side garage inside the structure, fire officials said.

The fire was brought under control and then extinguished by 9:30 p.m.
