Have any of you out there been successful in modifying stock bumpers to carry hi-lift jacks, jerry cans, spare tires, aux lights, etc? Mine are in great shape and I can't even come close to buying a new bumper nor do I have the skill or equipment to make my own. I see the need to carry an extra 10 gal. of gas with me on trail runs and don't want to carry it in the cab. Thanks for any input.
