If you were a Transformer Which Type of Vehicle would you be?

After watching Transformers: War For Cybertron Trilogy this weekend it got me wondering which vehicle I would want to be if i was to be a Transformer. This question would sometimes be answered when playing in the school yard and pretending to be one of the Autobots and Decepticons and sometimes picking which animal for a little Beast Wars action. However this question comes years later while having a different perspective and time to think about it.

First off I think that it would be fun to see a whole variety of vehicles and equipment get a transformable version, for instance seeing the vending machine transform in the Transformers Movie was a nice change and made for a good laugh or even a giant crane. It would be hard to pick just one but if your legacy was to be written at this moment in time which vehicle would it be?

For myself it would have to be a Chevy K1500 Pickup truck between 90-98 just the toughest box of metal out there with good reliability, I'd be thinking I don't want to much maintenance as a Robot and I'd want to be able to take a beating.

90-98 Chevrolet Silverado Z71 CK 1500

Let me know which vehicle you would pick?
