Review on 🔒 Proven Industries Lock Model #2516: Secure your RV/Trailer with our 2-5/16" Coupler Lock by Gregory Castellanos

I think this is one of the BEST locks on the market. I also checked out Castle Amp and GusHill. I didn't choose GusHill as they didn't seem to support their product. The amp looked VERY promising, but I liked the idea of hiding the entire ball and chain section. So far I am very impressed with the Proven Castle. Now they use make puck blocking which previously fixed some vulnerabilities. They also have an improved extra money lock on their site that is virtually indestructible, but I didn't want to pay the extra $100. Finally, their customer service was amazing when I called to ask a few questions about the vulnerability and quickly provided me with options as well. I heard Gushil pretty much wiped his hands after buying it. Again, Amp Lock is a great brand and I can check out their other products.
