New superduty - 18" or 20" wheels
I'm looking at ordering a crew cab shortened gas f350 with 4.30 axle to tow a Montana fifthwheel (11,700#dry). What are the advantages or disadvantages of the 18" wheels versus 20" wheels.

20's with 3:55 gears and I have no power issue at all, but im also diesel. the od of the 18 and 20 are the same, the theory behind it is a slight lower profile which will get a little less sidewall flex and better handing. the Michelins on the truck have the same load rating whether 18 or 20.
