I don't make it out to many games, so I miss out on some of these. A friend of mine has a bus decked out with couches and a full-screen TV in it, etc.
If I had 20k burning a hole in my pocket, I'd definitely pick up one of these and paint it maize and blue:
Feeling like your SUV blends into the crowd? In need of something to transport your groceries by day and a mobile party or arsenal by night? Meet the Badonkadonk, a one-of-a-kind "armored land cruiser/recreational tank". To look at it, one might think it to be a hovercraft, but in fact it runs on four off-road wheels, concealed by a unique industrial-strength rubberized flexible skirt that shields and protects the wheels to within an inch of the ground, while still allowing for enough flex to give clearance over bumpy and uneven terrain. The roof of the Donk features a guard rail and durable rubber matting, making it the ideal place to carry up to 3 friends or several hundred pounds of cargo. Slide open the roof hatch and you'll find the interior fully carped and cozy, with accent lighting, glove box, controls and room to seat up to 4 people, or 2 comfortably.
