In a previous post that I made on our used 2021 340RL that we just purchased. We had an Anderson gooseneck adapter already installed on the Roto flex pin box. I told the dealer to remove the gooseneck adapter before we picked it up. They tried to remove just the gooseneck adapter; it wasn't budging. They had a Rhino Box Pin Box available, so they replaced the pin box with the Rhino. I'm assuming that the Roto Flex rides better than the Rhino. This will be towed by my 2022 Chev 3500 LB SRW. I've read that the Rhino could be 4" shorter than the Roto Flex and a PITA to hook up on a long bed because the open tailgate may hit the front door of the RV. I will have the BW Companion hitch in the bed. Looking for some direction. I feel what I want to do is just purchase a new Roto Flex pin box and call it good.
