What is up?

[In The Ten Ring]

Now things are progressing well with my truck, moving right along on cleaning out the fuel system in preparation to getting it back on the road and I'm learning lots of new things here BUT.

A friend and I tried to push it backwards the other day...it was in neutral with the brake off and it only rolled about an inch and no more. Is it just that heavy (1972 swb) or is something wrong you think? It's been sitting in a garage for 7 years.

I'm 5'9" 164 lbs and my friend is 6' but slimmer than I am.
