There are a few different reason as to why you would be experiencing a leak with the Side Lever RV Kitchen Faucet with Pull Down Spout # 277-000129 installed. You could have it tightened down too much, not enough, or the threads on the faucet or your water lines may be damaged which would prevent a good seal from happening.
Try checking the possible issues that I mentioned above and if you are still having issues just let me know so I can help you troubleshoot further. view full answer...
We do offer just the king pin like the Buyers Products 2" Forged SAE Trailer King Pin with 1/2" Bolster Plate # 337KP20050 which gives you the standard 2" king pin for use with a 5th wheel hitch.
It is a good idea to have a qualified welder install the king pin, as the welds need to be sound to support the weight of the trailer.
I included a video of the Buyers # 337KP20050 for you to take a look at. view full answer...
