Front end rebuild?? or leave it be???

[allengator]

I need some advice!

My Dad used to drive this truck everyday.
in 2001 he had the entire front end rebuilt and aligned.
It drove like new!!

The following year he parked it.
Then I bought it from him so it would stay in the family and it sat ever since until 3 weeks ago when I got it out of storage.

I hate to spend money and time on things that dont need the work... so should I replace all the front end rubber??
Does it go bad sitting?

Thanks!
