Question:
I have a 2023 Forest River Sabre 37 FLL I am looking to buy the new BandW gooseneck adapter 1621. Will it work on my rv to replace 5th wheel? I am also looking at the 4inch Offset because I have a short bed ford. Will it be okay to use?

Hi Sonny, cool camper!
The B&W 5th Wheel to Gooseneck Pin Box - Lippert 1621/1621HD - 25K GTW - 3.25K TW # BW73RV will be a great choice! With your 2023 Forest River Sabre 37FLL having a 2,600 pound pin weight, this one will be the better option (the # BW83RV has a much higher pin weight capacity of 4,500 pounds and would end up being pretty rough).
You can also use a 4" offset ball with these as well. That's no problem at all. If you don't already have one of those, I will need to know the year, make, and model of your truck. I will also need to know if you have the factory pucks/gooseneck system or an aftermarket system (and which one if it is aftermarket).
Are you getting ready for a trip? If so, where you headed?
