### ⭐⭐⭐⭐⭐ Perfect Replacement For My Travel Trailer Regulator
*by W***W on November 9, 2024*

This is the second time I had to replace the regulator on my 2017 travel trailer. The first time was because of the mass recall. I had to figure out the regulator I needed based on total BTUs, figure out the length of pigtails and ensure the handles were the color I needed (dark green for most trailers), find / buy a bracket to mount the regulator to so it would stay on the holder, figure out the right self-tapping screws to get to mount the regulator to the bracket, and then get Teflon tape rated for propane. After all that work, and spending a lot more money than I did on this one, that regulator didn't last. So I found this one. Affordable. 12" pigtails with dark green handles. Bracket included. Auto-switching. Empty tank indicator. Enough BTU throughput to handle my trailer twice over. I changed the regulator out in less than 5 minutes and then tested it. The step that took the longest was cleaning the old Teflon tape off the threads. Easy. This regulator works like a champ. Thanks.
