You're not comparing today's pickups to those from a few decades ago are you?
The OP photo was pretty old.
A Ford TT truck had a 20 HP motor. While it may have been able to pull a lot, I believe it had a worm drive and wouldn't be able to go very fast. Just forget trying to get it up to freeway speeds.
We never had AC in any vehicle up until the 1990's or so. Certainly not the old pickups. That was what the vent windows were for.
I don't remember the MPG of our old half ton Chevy, but I heard stories of slightly larger pickups getting well below 10 MPG. My current RAM 1500 gets over 20 MPG empty, and likely can beat my old AMC Hornet wagon, as well as my old Ford Ranger 4 banger.
There is a reason why Service Stations have all but vanished, mostly replaced by mini-marts.
100,000 mile tune-up? When was the last time you had to hunt down some sand paper or a nail file to clean up your points? Even Spark Plugs are getting better.
I have had a few trailer flats, but I am having troubles remembering my last flat. I think I had a tread delam on my 1999 F150 a few years ago. Oh, I did plug my Transit Connect tire too. Anyway, reliability everywhere is going up.
