****, I say build the freakin' wagon!! Customize the crap out of it and come power tour, it will be the funnest experience hauling 9 or 10 people along! I think a roots style blown big block should power it along with a wicked, in your face paint scheme with bright colors with air brushings (people, characters, etc.), with some 20"-24" wheels rolling the behemoth. That would be awesome in my books. Just my $0.02!
