At approx. 0930 this morning fire crews were dispatched to a house fire on Hubalta Rd. SE. Upon arrival, it was discovered that it was not a house but in fact a motor home that was being stored in a commercial lot next to a gas station. Although the fire was brought quickly under control, the damage to the motor home was extensive as well as smoke and heat damage to other vehicles parked close by.   There was no damage to nearby buildings. The crews on scene, dealt with a number of small propane tanks that could have been a hazard to firefighting crews. The cause of the fire is still under investigation.
