It isn't only the knowledge, but also practical fitment.
Technically you should put the jack under suspension bracket on the axle.
But on most trucks even smaller bottle jack will not clear the tire easy.
When you call roadside assistance - they will bring floor jack, who has to go under axle pipe.
When those pipes are overbuild - they were not design as lifting point.
So when they usually are fine lifting 1500 lb empty truck corner, having them lifting 3-4000 lb of truck + TC is pushing your luck.
