The roofing material behind the front cap on the RV separated from the wooden roof and tore into large sections that could have detached and caused an accident. The material had to be quickly removed and a temporary mitigation put in place to prevent further damage to the RV as well as to mitigate risk to other drivers while in motion. Photos are available but the material is no longer available as it was disposed of. The wooden structure of the roof is not properly secured, most likely flexing, causing the material to separate.

The fire then damaged a hydralic line and hydralic fluid was leaking right next to the flame. Luckily we had a fire extinguisher handy and quickly disconnected the battery. Grand Design had an investigator come on site to survey…
