"I felt the explosion in my entire body," said next-door neighbor Evan Deleidi.

Three men had serious burns.

Peabody Fire Chief Jay Dowling said Tuesday afternoon that firefighters responded to multiple calls reporting an RV explosion.

Crews arrived to find the RV fully involved, with a concern that the fire could spread to nearby houses.

All three victims were conscious and alert.

Dowling said two of the victims, in their 40s and 70s, were flown to Massachusetts General Hospital in for treatment for their burns. A man in his 20s was taken to Lahey Hospital in Burlington.

Investigators believe the men were outside the RV. Authorities are looking into reports that they were working on the vehicle at the time.

Neighbors say the family was planning to head to the Grand Canyon with the RV on Friday.

It's unknown what caused the explosion.

"My house shook," said John O'Donnell, who lives down the street. "The explosion was very loud."
