It’s nice to know that I can leave my motorcycle tent trailer unattended and take a ride now without the worry of someone else helping themselves to my trailer when attending a large motorcycle rally.
Dave, Eugene, Oregon
I love my new Megahitch lock for my new Jayco. Now it is time to get the cable for my generators. Thanks for a great product. The best trailer hitch lock you can buy
Bob, Urbandale, IO
Your coupler lock is like no others I have owned. I truly feel comfortable with leaving my boat parked without being around to keep an eye on it.
Tim, Lafayette, LA
I bought an Airstream in Oregon and seen your product at the reseller. When I got back to Las Vegas I went to your website and looked researched it more. I really do think it is amazing.
Dane, Las Vegas, NV
I have lost 4 trailers in the last 10 years. All had coupler locks on them that did not stop them from being stolen. I think that with your Coupler Vault trailer hitch lock those days are over. I have never seen a product like this before. I think you have hit a home run with it.
Craig, Denver, CO
Good morning Mike,
I attached the hitch lock yesterday, and am impressed. The Airstream hitch itself seems welded, so don’t see what else would increase security. Once I start traveling, I’ll talk with others and see what they do, and what theft patterns emerge. You have a wonderful product.
Thank you, David, Dayton, Ohio
I purchased on of your Trailer Hitch Coupler Locks from a reseller in Florida. I have owned other trailer locks before and realized that I was only putting something on there that would slow the thief down. I have had two trailers stolen over the years so I decided to spend a little more and give your product a try. I am very impressed. Though nothing will prevent a thief from stealing something if they want it bad enough the Coupler Vault will certainly not make it easy for them. I watched your videos on your website and seen how you tried getting your lock off of a trailer. I decided that I would try it myself. There is no way it will come off without a cutting torch. Thanks for making a great product.
Jim, Clearwater, FL
Amazing….. That is the only word I can find to describe your product. Thanks for giving me the security I was looking for.
Steve, Littlerock, AK
When I purchased your product I was a little skeptical. I have bought other locks in the past and they were useless. I am a contractor in Colorado, and I have my livelihood in my trailer. In the last 12 years I have lost 4 trailers, and everything in them. I got your lock and put it on my Vault on my trailer.
Thanks, Jerome, Denver, CO
