Can you tell us what the other upgrades are? I haven't seem anything about them.
It actually seems to generate a lot of confusion. If you look on the towing guides it will state that the max tow capacity is only possible with 20" wheels, but it does not say any more than that. This leads many to believe it is based solely on the smaller sidewall leading to less flex. This was my impression as well, and my clueless dealer told me no different when I purchased.
It is not until you dig into the order guide that you see a bit more. There is a small note under the "Max Trailer Tow Package" line that says,
Note: Max GCWR/Max Tow only achieved on SuperCrew® equipped with 20” Wheels. These trucks will also
come equipped with max springs, steering gear and upgraded stabilizer bar for this configuration. While I don't need the max tow rating, and have no issues with power, these adds would have been a nice boon to truck stability had I done enough homework to understand before buying. They had the truck I wanted with both the 20's and the 18's. I didn't want to spend a thousand bucks on aesthetics, so I didn't. If I knew then...
