Just a thought on building a bigger and bigger deuce, why not just start with a 5 ton? Bigger tires fit with no mods, super single rims are easier to find, no axle strength issues, better brakes, power steering... And bigger engines fit fairly easily, just pull the 250 and put in a big cam version, or whatever other motor you like. just my 2 cents, but it seems like it would be alot easier then using a deuce if you want to go really big on power, tires, load capacity or whatever. If it's a size issue, you could use a tractor and through a 12' deuce bed on it. I know half the fun is building it, but if you want something BIG, start with something already fairly big. To me it kinda seems like tring to bread a really large chiwawa..just get a rottweiller
