This what I found Sunday 9am when I got to my warehouse. Total loss. It appears it started in the battery compartment. I did not have coverage for the trailer but the building and equipment are covered. Check your policies everyone and make sure you are covered. Trailers generally need separate coverage and so does your tools. This was a freak thing. Fortunately the fire was contained in the trailer other than smoke damage. The fire department was changing shifts and saw the black smoke coming out the turret vent a couple blocks away and that saved the building. The truck attached was unharmed, crazy! Estimate is around 25k for trailer and equipment and don't know about the damage to the building, ie: cut 3 holes in the roof and 1 in roll up door 4' x 4', and bashed the walk through door in, and smoke damage.
