Question:
Can I use the Helux pinbox to replace my Curt Rota Flex on a 2020 Vanleigh Beacon 39GBB? Many thanks!

Possibly! Does the Curt Rota Flex pin box on your 2020 Vanleigh Beacon 39GBB say Rhino Box anywhere on it or have a 807712 part number? If so, yes!
The only pin box bolt pattern as of (09/25) that the Curt Helux like item # C83RJ fits is the Lippert, now Curt Rhino Box. It's quite a bit narrower and only has 5 mounting bolts on either side like the picture below.
If you would like to email me a picture of the sticker on your 5th wheel trailer's pin box I'll be happy to identify the bolt pattern for you. It'll have a date of manufacture, LCI item number, serial number, and weight capacity.

Unfortunately not a Rhino box. Hopefully they will expand their options in the near future to accommodate other pinboxs. Would you have a recommendation for a comparable pinbox I should consider for a Lippert 1621HD? GVWR is 18,000 lbs with pin weight of 4,200 lbs.
