That "Nose Dive" Look

[crawdad]

I'm looking at getting another SWB 86 Chevy. I've been looking at two different trucks. Both same year, same model, same wheel base, same everything. One looks like it sits level, the other looks like it's doing a nose dive. Rear end sits up much higher than the front. I've had two of these trucks in the past, one had the nose dive look and the other sat pretty level. Owners of the two trucks say they are stock. Question is why do some of these trucks look like they are getting ready to plow the corn field with the front end and others look like they are sitting nice and level? Just curious.
