My S-10 weighed in at 2700lbs without the bed on it. Without me in it and about a 1/4 tank.
I loved my S-10. But going from a fullsize to a small truck you probably won't be happy. Although I did have more leg room in my truck, mostly cause it was ext. cab, then any fullsize i've been in.
If I was you, i'd keep the truck. You already have a V8, and you probably won't be happy with the power out of the V6s.
Trust me, I love first gen S-10s and still wish I had mine. BUT I love the feel of a fullsize and of course the V8 power.
