So the electrical would be when I shut my truck off in park I cannot turn my key completely back to release the key so therefore Iam killing my battery leaving the power on as far as the tires theyare rated for 50 or 55,000 miles I have 37,000 miles and I have no tread left and as far as my drivetrain when accelerating onto a highway pulling my fifth wheel camper that is 16,000 pounds loaded the truck box really bad as far as the crash warning breaking system it does not break
