Some facts.
Deuce front fenders and M105 bed are about the same width. Just over 7' I think. The 5 ton is 8' wide at the front fenders. I don't think a truck will look right with the back bed narrower than the front end.
If you plan to park with other vehicles at Lowes or walmart, that extra foot of width will kill you. Same is true for the length. A winch will also add some length.
Gross weight is much more comfortable with a deuce. My bob deuce was easy to drive, steer and brake. It weighed 11,000 pounds. I don't know how one could end up at 8,000 but stanger things have happened.
If you plan to do some serious turning and load hauling, the 5 ton springs will out perform the deuce all day. And the power steering is a great plus.
In the end you just need to decide what you plan to do with it and how all these things will factor in. For what it is worth, don't believe half of what you see and read on here. Pictures are very deceptive sometimes and some of our fellow SS pals are quite full of them selves (not suggesting any one on this thread qualifies). Have fun.
