UPDATE AT 11 P.M.
James Farran suffered second-degree burns on his arms, but he is stable. He recalls how he survived the inferno.
"It was hot. And I was in flames."
Farran says he just got the RV. He had been working on it for two weeks. Saturday, he went out to try and jump start the van.
"Just all of a sudden boom - it lit. And I was stuck right there. Everything was so fast. It was unbelievable."
He ran away from the scene and went to his parents' house a few blocks away on Rawhide St.
His mother, Jeannie Hutchins, says, "I really didn't know what was going on."
Looking at what's left of that RV, it's hard to believe James only suffered burns to his arms.
"I mean I was happy to death that he wasn't burned worse than he was," says Hutchins.
James and his mother are staying positive. They are grateful for a second chance at life and the fact that he didn't lose his sense of humor.
"I didn't lose my hair," says Farran.
UPDATE AT 3:42 P.M.
The Clark County Fire Department now says that this case is not arson.
CCFD officials say the man was attempting to jumpstart the RV when the fire accidentally started.
He received burns to his arms and was taken to the UMC Burn Center in stable condition.
