Is it worth doing a wheel alignment on a sierra.just wondering because there such a small wheel base.thought it wouldn't affect much

wheel alignments are always good unless you like your tyres going in 2000Kms or crabing (drifting sideways when your going straight) or death wobble. (insert list of other problems bad wheel alignment causes here).

Depends - have you either replaced or adjusted your tie-rod lately?

The only adjustment a wheel alignment will do on a Sierra is the toe-in, or maybe the straight-ahead direction of the steering wheel (which you can do properly yourself).

My Sierras haven't had a wheel aligment since I bought them. They'll never need one unless I replace the tie-rod.
