One of our local communities (not my favorite builder's) had a cabinet truck catch fire. They were running the generator in the truck and something caught fire. I want "a big ball of plastic laid on the muffler" in the office pool.
It ended up totalling the truck, two houses worth of cabinets (8 weeks out) and lit up the porta potty. The fire marshal is investigating but he has nothing to go on ... <rimshot>
Seriously, is there a rule about running a generator inside a box van?
