another idea in addition to greenbacks in your "pocket" is load a few hundred dollars on a prepaid debit card to use only in a "truck" emergency. I say prepaid debit card because of the fee involved. set it aside in a safe place in the truck seperate from the cash fund, because this debit card would be a secondary emergency fund to rely on if the cash fund we're needed, such in a case of DOT. Use it only when necessary and the fee that comes along with it would be a motivator not to use it too often to avoid the fees and you have an emergency fund to use at the pump, restaurant or wherever just in case.
