content: I purchased this adapter (47185) at Walmart. It is ruggedly consructed and easy to install and works great. The real reason for my review is to commend the customer service at Hopkins Mfg. Some how I misplaced the mounting bracket that came with the adapter when I was working on the wiring and drilling mounting holes. I called Hopkins to buy another bracket... they said they will send me one for free, and 36 hours later it was at my door! Thanks Hopkins.
