I always like to learn about the old equipment. I'd love to get into collecting military trucks (mainly the 1 1/4 chevys), but I have enough project trucks around home that never get any attention(maybe someday I'll have the money to do that stuff). I wouldn't mind getting one of those 1 1/2 trailers that seem to get auction off though.All I can suggest is learn all you can about the old stuff, its really VERY interesting to see how it was done back then and how it compares to Now, you can then come to your own educated ideas as far as what is better or worse, it truly is a very great hobby!
