All you need is an old Dodge Sedan.

That is so funny i laughed my ass off. man that was great. You can not make that up!!!
Put some fat wide mud tires on the back, and bring on the team of horses to pull it out afterwards ;)
(skinny tires were the saving grace, as well as a finite depth of mud)
I had to watch it twice.
Wow. Those spokes must act like paddles in the mud, lol.
Skinny helps too. Less mud to displace, and float on. They sing right down to the hard stuff, and move on out.
I've driven a Jeep CJ on 35x12.50 mud tires. It just floated like a beach ball on anything softer than pavement. On snow, it was a real terror. On ice, it would simply oscillate in it's own length like a prostitute hung from a ceiling fan.
I wrecked it in 1995, and both it and I came away from it a little worse for the wear. It lost some engine oil, and I lose some blood. I've never driven it since, and never will again. My kids can fight over it when I'm just a chunk of meat in the ole pine box...I want nothing to do with it. My dad bought it when it was a couple of years old, and I was 5, or close to it.
Jeep: just empty every pocket. Laugh...until you own one, and find out for yourself.
I've had 3 XJ's and 1 ZJ, I know what you mean.
