Judging by the poor standard of bonding that I've seen on light aircraft I would certainly be concerned about high voltage and fuel.The ute mentioned probably has a welded body, your typical "lighty" has a riveted fuselage. Your average ute has a welded metal tank, an aircraft has fuel sloshing around inside a riveted wing or even inside a rubber bladder. Those facts alone are enough for me to disregard this suggestion.
Maybe better to take your dog??
