Speaking of towing, or even hauling for that matter. I have a 5.4 gas e350 12 passenger. I am towing a trailer occasionally with a rather heavy tongue weight. I gutted the inside of my van and did the sienna seat install. Just yesterday, I wound up picking up a Honda Eu3000is generator yesterday, and I noticed, with it just inside the doors, that my suspension felt different. I would imagine with the seats gone, this is what it would feel like loaded down, but when towing my tailer, the van just does not handle the way I would like, and the back end drops more than I would like. I am running a WDH system now, but have any of you found ways to improve handling while towing without completely messing up ride quality while not towing? I have been considering adding a leaf. I would rather not bag it, as I don't want to have to constantly check air pressure.
