Update on my search.
Don't have good luck to salesman. They misread the emails, send me to Ford site for options and are not able to add other options than main site does.
I can't have dual AC on XL, no custom paint and to top it, the offer on custom order truck is $1000 below MSRP.
Comparing to $8000 discounts on stock trucks, I can have loaded lariant from the lot for close what my custom build XL would cost me.
Have met well working salesman in Arizona, but distance makes it difficult.
In the mean time found this used dually. Shall I make an offer? ;)
Nice dually
