Cristobal D. P, 66, was found inside the cab of the vehicle last week after the emergency services were called.
Witnesses have described hearing three explosions coming from the vehicle at Avenida Salvador Dalí in La Colina, and a column of smoke that sprouted several metres.
Firefighters, who took eight minutes to reach the motorhome, said that the vehicle looked like a ‘ball of fire’ when they arrived.
The cause of the fire is under investigation, however, police suspect it was an accident.
