I'm amazed at which particular features or items turn someone on about a car/ truck/ service. A 68 RFE transmission is the old 727 unit with an overdrive added to the rear as an afterthought. In the early years of overdrives, those were absolutely unreliable. With many engineering and hardware upgrades, they have gotten better... "This is a different truck" evokes a possible biased conclusion that these changes caused the truck to be at a level not previously considered possible, in a positive way. Conversely, it could mean something else to others.
I'm thinking that this shop has a pet kangaroo? I knew a guy once who had a pet White-handed Gibbon Ape, and would show his customers, to ooh and ahh over. Laws have changed such that having a pet Gibbon is no longer legal. But why? I can only imagine the Vet bills and liability should the ape bite someone! (A HUGE possibility).
Lately, the EPA has been aggressively going after Mom and Pop Diesel shops and shutting them down and confiscating everything; leaving the owners looking at prison time. This was related to me just yesterday by Michael Herzing, Host of "Let's Talk Wheels" radio show where he delves into all things and trends, current and past, in automania. And OP points directly at them, by name and locale.
