Review on Trimax SXTC123 Stainless Universal Coupler by Michael Hellewell

Don't waste your money on this. Spend a little more money for a stronger lock. When we first received and used it, it was great. After standing in our RV for a month it was so rusty that even after oiling it was difficult to remove the lock. So we hit it with a piece of metal to move it and the long part of the lock bent and broke. We didn't try to break it, we just tried to knock it out of the RV. So if we didn't try to break it it means someone trying to steal our camper wouldn't have a problem with it. So, as said, save your money and choose another product.
