How to Determine What Pin Box a Trailer has For Trailair Replacement


Im not 100 sure, I think my RV takes a Lippert 1621 pin box. It is a 2008 Timberland RPM Series, Model 295FB. I cannot find contact information for the manufacturer to give them a call and ask By the measurements guide its the closest one by far. I uploaded one picture and I have more pictures of the measurements, just cannot get them to upload.Is there any way to know for sure which pin box I have? Also, is this pin box compatible with the Reese Hi-Rise 9480 fifth wheel hitch? Thanks!


Expert Reply:

If you have a Lippert 1621 pin box on your 2008 Timberland RPM Series, Model 295FB the measurements will match exactly what is in the chart of the FAQ article I attached. Close isn't enough, they have to be exact. If you wanted to take all of the necessary measurements and email me back with the exact measurements I can see if there is a replacement that would work.

Pictures of the measurements can be misleading so that wouldn't be necessary. If you could give me the needed measurements for 2a through 3c of the chart in the FAQ I attached we can determine what you have.

Is there a sticker or plate on the pin box there should be the pin box brand and model number listed there.
