I spoke with my contact at Trailair and from your serial number we were able to determine that your trailer came with a 1621 HD pin box which is a long pin box style. I was unable to obtain the exact part number for your Trailair pin box but from…

The MORryde Cushioned 5th Wheel Pin Box #MR84VR weighs right at 190 pounds. Due to this, it will ship freight. Just in case you needed, this is designed to fit 14,000 to 18,000 pound trailers with the Lippert 1621 and 1621HD pin boxes.

Thanks for the pictures! Since your 2022 Grand Design Reflection 303RLS came with the CRE3000 equalizers you will need three of the MORryde X-Factor Crossmember item #MR33WR. It looks like you have the standard 3" wide frame hanger so all of the…

The MORryde Cushioned 5th Wheel Pin Box for 14K to 18K Trailers w/ Lippert 1621 and 1621HD #MR84VR is listed as being 190lbs. You'll probably want to have three people to lift the pin box in place and get it bolted, unless you have access to a…

Thank you so much for the pictures! That is exactly what I need. Your 2023 Solitude 2930RL has what's called a Lippert Rhino pin box. The Rhino Box, like the Lippert 1621 you mentioned, is a specific bolt pattern and to replace it with a MORryde…

The 3,500 lb capacity Curt RockerBall Shock Absorbing 2" Hitch Ball #C94CR (40246) does not have a softer cushion than the 7,500 lb RockerBall #C40047. The cushioning is the same and the difference between these two is the capacity, of course,…

The correct MORryde Cushioned 5th Wheel Pin Box for a Grand Design Reflections 337RLS is part #MR84VR. This pin box will do a wonderful job of helping smooth the ride due to the internal cushioning which reduces road shock.

You could remove the roof to fix the staples but that would require a ton of work and can be costly, which is why Alpha said it would be overkill. You could just hammer the staples back down and just use some self leveling sealant like the Alpha…

The answer to your question will depend on what kind of surfaces your tow vehicle will be parked on when you hitch/unhitch the trailer. If you are going to find yourself pretty consistently on level, even pavement, then a fifth wheel hitch whose head…

There should be a sticker or plate on the pin box itself that lists the manufacturer and model of the pin box. If it is not present then there are some measurements you can take to determine the model of the pin box. I have included a link that…
