HELP! Looking For Locking Gas Cap on Thor-AXIS

[dagoDenver]

Does ANYONE out there know Brand & Part number for a locking gas cap on a 2017 Thor-AXIS motor home Ford E series-gasoline? Things I've read & done:
1. NAPA Locking Fuel Cap 703-1723: Screwed down but no lock/turn & pops off.
2. NAPA Locking Fuel Cap 703-1720: Wouldn't cinch down to even try to lock.
3. Amazon (Stant 10508): It cinched down fitting perfect BUT turn the key to lock & it did the same thing as #1. Turn it to the left & it would pop off!
ALSO tried Locking Gas Cap that fits Ford F-150-it didn't come close to fitting.

SO...If you have a 2017 Ford E series, gasoline-12 cylinder That's connected to a 2017 THOR-AXIS. MOREOVER, a locking gas cap that fits AND Locks,so when it's turned it stays locked & cap doesn't come off in your hand. PLEASE, PLEASE, PLEASE-send me the info so I can stop repeating steps 1,2,3,. Thanks!

(Some of those threads are for the F-53 chassis, don't know if it uses the same cap as the E-Series based Axis/Vegas units.)

The one thread suggested a good idea: Take the RV to an auto parts store, take the gas cap in and ask them: "I need a locking version"--see if they will let you try some until you find one that fits.

I wanted to say Thank You! for those who've responded with my search for a 2017 Thor-Axis locking gas cap. Please if anyone has one that works-send me the info.

Since I'm new at this & I don't want to get out the winter cover just yet. We had a snow storm that started Friday evening - Sunday morning. I was wondering does anyone throw on a big tarp over the top & then rope cinch it down & works? Boss suggested I ask this!
