Dodge Repair Questions? Ask a Mechanic for Answers ASAP
I fully understand your pain. They have gone cap less with a lot of the vehicles as well. I know of companies that sale caps for the fuel side of the set up so that nothing gets into the filler neck unless you want it to.
Its not a locking door or cap but a cap none the less.
Geno's Garage also offers the locking door for your truck as well. It comes in brushed and polished.
With the two items you can stop any one from getting access to the fuel filler and also with the cap....make sure nothing gets into the tube with it being cap less.
