My trucking career ended in '97 so everything I drove was earlier than that. I've driven Autocar, Ford, Mack, White, Brockway, GMC, IH, Freightliner, FWD, Oshkosh and a Peterbilt cabover. Started in White 9000, then a Road Boss, those trucks were rattle traps. The fenders flapped and there were so many rattles and squeaks inside it was very fatiguing. I wasn't a fan. The Mack DM600 was very reliable but uncomfortable for me, I'm 6'4" and legroom was sparce. GMC and Brockway were much like the Whites. The FWD and Oshkosh were purpose built for plowing, not comfort. They plowed well. IH got the job done but there wasn't anything there that made them memorable.
It may sound odd but my favorite truck to drive was the Ford L Series. Dash layout was very user friendly, visibility was amazing and they were the tightest turning trucks I've ever driven. I had a lot of miles in them and they're fond memories.
I mentioned the Peterbilt, it was a cabover and after a lifetime of the Peterbilt hype I wasn't all that impressed. It might be that it was a cabover but I've sat in conventionals as well and thought them to be small and cramped. These are my experiences.
