I’ve seen posts on the web where people claim that, since the factory has to assume that you may need to change a flat tire when the truck is fully loaded, that they therefor provide a jack capable of lifting the wheel with a full load on board.
Of course, people who put truck campers on pickups often exceed the factory weight ratings.
Personally, the factory jacks look so cheap that I really prefer to carry a bottle jack.
For what it’s worth, I’ve chosen to invest in a SafeJack kit from Bogert with it’s various adapters. Since I’ll be moving this from vehicle to vehicle, I look on it as a lifetime investment.
I don't like to make plans. They cause the word "PREMEDITATED" to get used in court!
