Here is what I have concluded regarding scale commercial trucks.
No hobby manufacturing company now offers a complete kitted "all in one box" scale R/C model classic
Kenworth truck anywhere in the world that I know of for the serious hobbyist. We must exclude Kenworth toys for little boys. Kenworth scale modelers from complete manufactured kits are limited to static models that sit on the shelf and collect dust.
I am now finding the current R/C market to be very lame.
