What do you guys think about this thing? http://www.4wpw.com/4wp/products/productline.asp?cat=ACC&man=ARBJ&prodline=4534&catName=General%20Accessories Seems pretty cool to me, although kind of expensive. Sure seems easier to use and store than a Hi-lift. It goes 30", which is probably good enough for trucks that aren't uber-lifted and/or super flexy. Not sure whether it's advisable to put it under the axle. I also think I'd rather carry a little 12V pump than use exhaust. It might be a problem with duals too.
