i believe he did it that way for ease of repair
ding ding ding we have a weiner.
Not that he hasn't thought about other options, but there are/were more pressing things to be concerned about as it was being built.
Not that things won't change there either.
He could have widdled that jeep out of a solid piece of aluminum if he wanted.
He would have whittled it out of styrofoam and then cast it out of aluminum if he could have melted enough on the grill.
