Even though there is more weight on the hitch, its effets on the truck are less cause its directly over the axles. A bumper pull that hitches several feet behind the axle gives the trailer lots of leverage.
Think of putting a pallet of whatever right at the back of the truck (half on the tailgate) vs shoving it all the way to the front of the bed. Same weight, big difference in how the suspension handles it.
One thing to keep in mind too, is GN's turn short and cut corners. You need WIDE driveway approaches to get into and out of. If you have a narrow drive, you may either have to change that, or stick with BP
