Eh…

Run what you’ve got I guess.

203 is a chain driven boat anchor, more weight than a gear driven 205 with less strength than a 208/241.

If you have options, I would choose either a 205 for strength or a 208 for light weight medium duty. The AWD 203 isn’t all you think it is, do some research on them before you decide.
