The Ranch Hitch Universal 5th-Wheel-to-Gooseneck Coupler Adapter # AM3100 will not work with any cushioned pin pox like a Rota-Flex, however there are a couple of options for you to make the Solitude compatible with your gooseneck hitch.

One option is to use the Demco Recon Gooseneck-to-5th Wheel Trailer Hitch Adapter - Single Jaw - 21,000 lbs # DM8550045. This allows you to keep your current pin box and will simply install over your gooseneck ball for an easy connection to your truck.

Another option is to use the Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter # RP85FR. This pin box replacement for 1621, 1621HD, and 0719 pin boxes offers air ride and a direct connection to your gooseneck hitch. There are other pin boxes that are compatible when you use the spacer kit # RP61301. If you go this route, let me know the numbers on your current pin box and I'll be happy to help ensure you get the correct fit.

Lippert does not recommend using chemicals of any kind to be used on the PolyHyde vinyl used on their Theater seating like the TP27FR as it can damage the polymer coating. Instead I recommend using warm water to clean the theater seat thoroughly,…

The noise you described would be from the pivot point of the Rota-Flex. I spoke with my contact at Lippert and he said that typically when the noise you described is heard it is because there is a gooseneck adapter on the pin box which isn't…

The thing that causes the noise you are experiencing is actually the hitch you have and not the Roto Flex. The biggest factor in how much noise you'll experience when towing a fifth wheel trailer is the hitch itself since it has moving parts and…

The Rota-Flex pin boxes will work just fine with the B&W Companion OEM 5th Wheel Hitch for Chevy/GMC Towing Prep Package #BWRVK3710 that you're referencing. To our knowledge the only standard 5th wheel hitches that the Rota-Flex isn't…

You will have to go with a sliding hitch to allow the trailer to make tight turns. For a trailer 8 feet wide the only bed length that's going to allow 90 degree turns without a slider is a stationary hitch. That being said you have two options.…

If your current springs have 5 leaves then going to a 7 leaf spring will increase the height of the trailer a little and make the trailer more susceptible to sway. Regarding capacity if you go with springs rated higher than what is required it will…
