We will be taking both the XJ and the Suburban. I think the Suburban would be maxed out loaded down with camping gear and towing the XJ on a fullsize car trailer, so I might drive the Jeep and Shannon drive the Suburban. Or we might flat tow the XJ. Both have to get there and both have to come home, we will figure out something.
I've run the truck 1500 plus miles on a fill but that is at around $600 to fill it.A "group rent" instead of the all familiar "group buy"; interesting notion.
