I custom order my F350 after we sold the house and lived in the camper.
3 months wait at the time was not good, but having the truck that fit your needs like a glove was very good reward.
Fact that shopping in 100 miles radius, I found a dealer who custom build the truck with $5000 discount below MSRP.
Additionally not having 4WD (the only available at dealer's lots) saved me thousands in additional fuel cost, while 3" height difference made using much easier.
The only option I wanted and could not get with SuperCab was King Ranch trim. For some reason that would go only with CC.
But Lariat with with 2-tone pearl white was looking great.
