Question:

so im looking to replace the Lippert Rhino pin box and see there is a Curt Flex Air and a MR55QR. Can you please give me a little guidance on what is best to replace the Rhino?

Sure thing, we can help guide you on the right choice to replace your Lippert Rhino pin box, and both options you mentioned can be right for you, but it depends on your situation and what you are looking for. We'll go over both, with the correct part numbers to replace the Rhino being the following:

- Curt Flex Air 5th Wheel Pin Box # LC65VR

- MORryde Cushioned 5th Wheel Pin Box # MR55QR

So the bare bones difference is that the MORryde just has the rubber compound and pivoting (back and forth) skid plate, while the Flex Air has that and the air bag. But you probably knew that, right? So the question to answer here is what are you - Andrew - looking to improve as you tow?

The more economical MORryde is best if your trailer has a more moderate level of chucking, or back and forth movement, as you're travelling. The rubber compound helps control the shock of the king pin in your hitch, and the skid plate helps limit movement, so this is a nice upgrade for a trailer that is otherwise not too problematic in its movement, and you need that bit of extra help for a more enjoyable journey.

The Flex Air, meanwhile, has the same rubber compound and pivoting head, but the air bag adds another level of control. This is better to help control a lot of the up and down bounce that can uncomfortably occur on the road. It will also absorb any sudden jarring better than the Rota-Flex, so the Flex Air is the better choice if you have a particularly uncomfy ride, or if you are a regular on difficult roadways.
