Best way to secure a Max Coupler hitch when leaving the trailer in camp for the day


We've towed our trailer for 30,000 miles. 10000 this year alone. We've left the trailer hitched and unhitched in various gas stations, parking lots, campgrounds, and dispersed sites. We'll set up a game camera at campsites, but no one has yet been caught walking up to it after 8 years of travel

My method is a little different and may take a little explaining. My setup is such that I can use the traditional ball & cup or the Max Coupler and it takes, maybe 15 min. to switch from one to the other. Of course I have separate receivers for my tow rig. My reasoning is that for highway and Forest Service type roads the ball is entirely adequate. I will switch to the Max when I know the terrain is such that the Max is preferred or required. My reasoning is to avoid unnecessary wear on it. Plus it gives me a backup. So, most places I use the Max are difficult to reach. Where I camp is relatively secluded and that helps keep most thieves away and risk at a minimum. I end up not using any discouragement with the Max when it's connected to my tow rig. With the ball, however, just to discourage theft, I'll use a padlock instead of the normal pin on the cup latch since I'm towing through a higher risk environment.

Under most conditions, all you can do is discourage theft. In the wrong areas and conditions, if the thief wants it bad enough, they'll figure a way. If the area where I camped or the trailer is parked is high risk, I'll remove and store both sides in the locked tongue box. I have a long shanked padlock to install through an empty hitch hole on the frame to give a little additional discouragement.

I start with this:

And choose this most of the time:

Or the Max for the rough stuff (bolts have washers and nuts not shown):

And the padlock instead of the pin:

I got three locking pins with matching keys (so I only have to have 1), put one on the trailer side, one through the coupling, and one on the vehicle side and leave the whole assembly on the trailer. Like everyone said, you do what you can do to make it a little bit of work and then don't worry about it.
