Ahh, well, that's different. That looks like a weight distributing hitch with built in sway control. It's primary purpose is to transfer some weight to the front of the vehicle, trying to keep it as level as it would be unloaded. It's secondary purpose is to help prevent sway.
The alternative is a separate WDH and Sway system. Kind of like this one:
Husky Round Bar Weight Distributing Hitch Package - Husky 30849 - Hitches & Hitch Bars - Camping World
Since you want to occasionally pull with an explorer, I recommend you get some kind of WDH. And since you'll be switching vehicles, you'll need to learn how to adjust the set up for both.
