No one was injured in a two-alarm fire Thursday night that heavily damaged the Explorer USA RV Super Center in the 4000 block of Interstate 35E.
City of Denton Fire Marshal Rick Jones estimated the fire caused about $2 million in damage.
Investigators traced the start of the fire to one of two RVs parked under the building’s canopy.
“Both were energized at the time, so the air conditioning, refrigerator and appliances were in use at the time of the fire,” Jones said.
Since investigators did not find the fire to be suspicious, they turned the forensic investigation over to the insurance company, he said.
The blaze was called in at 9:05 p.m. to the RV sales and service business on the east side of the interstate, south of State School Road and north of Shady Shores Road.
Firefighters were able to contain the damage in a little more than an hour, according to department spokesman Brad Lahart.
“There was a lot of fire in the building,” Lahart said. “And northbound traffic on the interstate was shut down for a time, and we had a long traffic buildup.”
