Newer trucks don't always ride better. My daily driver is a 4wd with an offroad package and has a very stiff ride. The Sweptline 2wd trucks I've driven, with the front I-beam axle and leaf springs, didn't seem bad and maybe better in comparison. I'm sure the 72-93 2wd IFS trucks have an even better ride.

I was a passenger in someone's 2000s Nissan 2wd truck and it felt like riding in a luxury car compared to my truck.
