I use it for family road trips, work van(computer parts, low voltage wiring, home theater stuff) and trips to home depot. It will pull a boat two block to the water when the wife has her Wrangler.
I was looking to lower it a couple of inches for maybe better MPG, easier entry for the kids and me with junk, and for looks, the ass end now is so high, the tires look too small (stock 246/75/16). Every car has a good ride height somewhere between speed bump through the grill and 8" lift with only 31's. The van just looks too high. I was looking for 1-2" in the front, and 2-4" in the rear.
Needless to say, I have no real pressing major reasons, just a few small ones. If it is too $$$, too PITA, or too many problems, I will not even pursue it further. I was putting out feelers to see if it had been done.
