I don't collect it now but man the Big Jim Camper pictured on this page just rocked my world back in '74. I remember drooling over that boat and buggy set. Early Big Jim is just so representative of the early 70s, you can't get more peaceful than a guy who goes fishing. I still have my talking Big Jim backpack and it works, I should try and put some files of it up here.
Oddly enough, I saw a boxed Camper at an antique mall on the weekend, my four year old practically begged me for it. Big Jim has still got it I guess.
