This is what my RAM owners manual says, I have always done it this way for many years.
Jumper cable positive to positive on batteries. Negative cable end on battery of charging/jumping vehicle. Discharged negative cable end to a ground, NOT on the discharged battery.
Makes sense, you would want all the batteries using a common ground. The batteries on my truck died last year and I had to get the auto club to give me a boost. He connected his two booster batteries in parallel then hooked them up to my truck just that way.
