The fire broke out shortly before 4 p.m. at an RV repair center at Holland Motor Homes, which is located at 251 Travelers Way.
One family watching CBS News 8 coverage of the fire saw that their RV had been spared from the destruction.
Georgann and Gary Mills said their 40-foot RV was perfectly intact the next day. The fire destroyed nearly eighteen motor homes, as well as the Holland RV service building. Their RV was being repaired at the time and when they first heard about the fire, they were sure it had been damaged or destroyed in the flames.
"We knew where the motor home was and we had a feeling we were going to be looking at getting a new motor home," said Gary.
However, their fears were calmed when their daughter sent them a picture of their RV intact.
"We got a nice picture from my daughter who lives in Poway from the Ch.8 program. The news program that she had been watching had a picture of our motor home with all the firefighting efforts going on behind it," said Georgann.
Gary said that their motor home was at the RV center to have the propane line repaired, which led him to believe that propane may have been what sparked the fire.
"That’s what's so common with motor homes is propane problems. It could have been my motor home that started the fire, instead of just being part of the fire," said Gary.
Fire crews and ATF agents are continuing to investigate the cause of the fire.
