After a successful fishing trip we wanted to cook a few. Friend had his electric knife in the grub box but there was no electricity to run it. Noone had experience nor suitable knife to do it old school. I said we can just plug into the block heater on my F-250. Snickers and guffaws abounded but I paid them no mind as I reached under, plugged extension cord in then started truck and set high idle. Gasps and looks on their faces were absolutely priceless when the electric knife sprang to life. As you might expect they wanted to look beneath the hood but I kept keys in my pocket and told them I didn't want them messing with my truck. I shrugged and said it came that way when questioned about plug being female and such.
How could that be?
Inverter with cord at opposite end of bumper than heater.
How could that be?
