Well seems some of my rv research may come in handy.
first check out this online store. Prices are great and service even better.

I have linked to same lock as Gary just for price comparison but do a little digging on that site they got all sorts for trailers hence the name Etrailer.
Now you mention the trailer jack. Well what i did with my travel trailer was to take the hassle out of hooking and unhooking with an electric jack.
The beauty is if there is no power that sucker aint going nowhere.
I tried to look ahead in this case. With all due respect you a tad older than i am and for the $150 odd dollars that they can be had for i would consider fitting one to your trailer especially if you considering putting a battery in it. Then when you park set it up so the battery is disconnected when locked.
This will save your arm and shoulder from heavy duty winding and no need to lock anything like the winder.
I recently put our new travel tailer out to storage and in doing that i set the jacks down and put a healthy chain through the two wheels each side and locks.
So again to speak to Vaughns point, my trailer is a heck of a lot more hassle to steal than the others around mine that were set ready to be hooked up and taken.
Btw if you dont have the scissors jacks on your trailer you could fit 4 to each corner underside for not much loot and then you raise or lower them with a 3/4 socket fitted to that impact driver of yours.
I used my Dewalt 18v and it worked magically. Never had such and easy time ever before as i did with those jacks. Sharing the load on the jacks will help stability and take some weight off the tires too. If u can make em lock down the good luck to the thief thats gonna try tow a trailer away with an electric jack thats down and dont operate and 4 locked down jacks.
Then i am with Darrem on the break in aspect. Just add a voice annunciator to the alarm to imply that u are watching.
Sure is fun project you got going. Lots of prep work to get setup but as i say to Linda its a one time deal do it right first time. It will take a little
investment but will be worth it in the long run.
P.S. Another thanks to Jim Delaney....i think if i am not mistaken it was Jim that gave me the idea of using a drill to lower and raise them jacks.
