Since you sent me a PM on the subject and now are asking some of the same questions I will just post my reply to you as it's no secret.
That's great! You do have the puck system. You also have a LongBed, that's great also!
There are two B&W hitches for your puck system, BWRVK3300 is 20k rated @ $1,044 and the BWRVK3305 is 25k rated @ $1,262 at Trailer.com.
So it depends on the LOADED weight of your RV what one to buy. Personally I would go with the 25k as it will cover any 5er you can haul with your truck.
"ford truck guy" that posts on here recently ordered a 2020 F350 LB SRW and also ordered a 20k B&W since his RV won't weigh over that much.
Since you don't need a slider there is no reason to discuss PulRite.
B&W is the most simple hitch to hitch and is a no question if you are hitched setup. The 1" thick machined jaws hold the kingpin tight with ZERO rattling about like many other hitches.
The pivot points on the head are right at the same elevation as the kingpin connection so you will not have chucking associated with the hitch like Curt Customers have reported.
B&W is simply the best non air ride hitch on the market! One good reason is they are easy to hitch and unhitch when the truck and RV are on different planes. Curt for example can be VERY frustrating to use in those conditions.
I have owned other brands but B&W puts them all to shame!
Another bonus IMHO is the fact B&W hitches and products are all Made in USA.
Any other questions I can answer let me know!
