Actually there is little choice and the gearing will be fine. 3.31 was used with 18" wheels and 3.55 was used with 20" wheels. The overall effect was the same with the engine turning the same RPM at the same speed. One exception is that the snow plow preparation package and the camper package had the 3.55 with 18" wheels. A diesel turns at a much lower RPM than a gas engine and you should not compare the gearing between the two. Now if you really want something to unnecessarily worry about, consider the fact that 5th gear is overdrive and 6th gear is over overdrive.
The 3:55's were available with 18" wheels if you added the camper package.
OP, you'll be fine. Plenty of torque, with the six speed will get er' done!
