Another vote for the Max. We tow a trailer, have no children but do travel with 3 small animals. Can't imagine having enough room for them and their "stuff" (along with our stuff) in the regular length. And, as someone else mentioned, the under floor storage in the Max is quite handy--I carry a small air pump, a few big wrenches and other stuff in it. Even if we didn't tow, I would have bought the Max for the times I need to carry lumber, etc. that is 8 feet long without having to try to fit it in and hang over the front seats or out the back. And it is SO nice to be able to lay a 4 x 8 sheet of plywood, foam insulation board, etc. completely flat with the tailgate closed. Practically none of my friends with pickup trucks can even do that trick! Of course, those are my needs and uses; if you never haul that sort of stuff, doesn't make much difference I suppose.
