I think it's just that the long beds are just more common, therefore not as desireable to some. I really like the long beds and longhorns, but they are everywhere around here. I like to be different, so when I found a short bed at a good price I scooped it.
I agree with you on the trend of slammed, wild colors and 20" plus wheels, as I prefer a more subtle sleeper look. But others have different tastes.
Old cars are cool too ( I wasn't looking for a truck when I found mine) but cars are WAY over priced these days.
Here's to long ones! Uh, that didn't sound good.
