You damned if you do and your damned if you don't! Either way, the best way out is to keep it...get the extended warranty, refinace it and hold on to it. As long as you honestly can afford the gas then the truck will last you years! I can't hoestly see you taking a massive hit on it just to get rid of it, and then taking another hit on buying something else. Your worries about California are very minor, there are so many more positive reasons to keep the truck then there are negatives. Your number one headache is the gas prices. Keep the rig.
