I have had some questions as to why I am selling the suspension and upgrading to 4WD. The only reason is because we use our van as a tow vehicle for our boat, and obviously also use it for launching/retrieving the boat. I operate the boat and my wife operates the tow vehicle. We have always had a 4WD tow vehicle, so now with a 2WD van she is downright terrified to launch/retrieve the boat. After a (long) summer of slipping the rear tires I will not do it again. I tried to teach her to feather the brakes and finesse the go pedal, it just wasn't happening. It was either sell the van, which we just bought, or spend the money to upgrade it to 4WD. The van makes a GREAT tow vehicle for us, no truck or SUV on the market can duplicate it for us, especially after I get it where I want it.
EDIT: Here is a photo of the reason why I am upgrading to 4WD. Boat and my lovely wife standing on the dock.
