Blucolr...the part of Texas you're heading to is rather sparsley populated, compared to the N'eastern states. I run US287 thru there to Amarillo/Borger quite often, & don't recall ever seeing an expediter. I see most expedite trucks between Dallas/Laredo, or along I10 & I20.
There is a small Freightliner dealer in Wichita Falls, nothing else 'till Amarillo. (edit to add, just checked, could not find a dealer there.) All larger dealerships are in the D/FW, San Antonio, Houston triangle. (along with 75% of the Texas population)
I kinda wish there was a market for the expedite trucks down here, but, the petro-chemical industry & oil patch want flat-bed hotshot trucks, so we provide
Have a safe trip (the black & whites really, really like US 287...)
