Which era of 49-72 trucks have the most leg room?

[lotus]

something I was thinking about on my way to work this morning.

I have not rode in a 60-66 truck since i was ten and I can't really remember how they are with leg room.

I have rode in plenty of 55-59 trucks and they have a lot of room. How does the 60-66 compare to the 55-59 era trucks?

For that matter if you had to rank them.

47-55
55-59
60-66
67-72

from least leg/cab room to most.

Only reason I ask is I am 6'2" with a slight gut and man i hate being smashed into the steering wheel. haha.
