Step vs. Fleetside

[FatRanza]

Hello all,

This is my first post, forgive me if I've posted in the wrong area of the board. I've tried searching the board for this info, but didn't find anything, so here goes...

I am shopping for my first truck (at 48 years old!) and could use a little advice. I've decided on a mid 60's to early 70's Chevy, but here's where it gets dicey...in short, Stepside or Fleetside? What I want is an everyday truck that is the most practical for general truck stuff. I'll admit that I am partial to the look of a stepside, but I don't know the pros and cons of the two beds. Why are there there two different bed styles anyway?

The other issue is engine. Can I get by with the straight six for towing all but super heavy loads?

Thanks Guys,
George H
