Oh the 20s look nicer!
If you are building on line, it will not let you select certain options if you chose a certain chassis or other option.
Like there was on the 4.10 gears. If you selected a diesel engine, than you got 3.73 gears. If you then select the 4.10, then it will kick it back to the 6.0 gas, as that is the only way to get that gear option. ( this was in tbe '14 hds, I havent looked on the 15s yet.
It was doing it the same way on the 3500s on the 20" option, it wouldn't be available unless you picked the 2500.
