I think about these things more than I build them, but I have a lot of buddies who are hard core rock crawlers. Watching what goes on I have a hard time figuring out what is the best size vehicle to make a crawler out of. Big ones seem to go over bigger obstacles but little ones get through tight spaces better. Light ones are easier to get 'unstuck.' And they all get stuck once in a while.

So for an average guy to build a budget crawler (if there is such a thing,) I was thinking something like a Comanche would be about the right size.

Whaddya think?
