richard5933 Report post Posted November 19, 2021 They do make locking fuel caps for diesel tanks. You've got to get the right one for your tank though, so it will take a little checking. Might be a good idea to go to a local dealer for whatever chassis is in your coach (ie Freightliner). Here's a few of the ones available: https://www.budandtonystruckparts.com/search?q=locking+fuel+cap&gclid=CjwKCAiAs92MBhAXEiwAXTi2533nz9O3UKl24LSBVikxLcen1kxHiCFAewkpeHh15id_Y29sgMJhbRoCbkwQAvD_BwE Another option, especially if both your fuel filler and your DEF filler are behind a small door together, is to put a lock on the fuel door.
