Looked at a bunch of trailers before I ordered one. It is very expensive but BRX trailers are very well made and use high end components. Off grid trailers are very nice as well. Their Pando trailer is about the same price when you option the extras that are standard with the BRX. I’m sure either trailer would be awesome.
Comes standard with max coupler, maxxair fan, rock sliders, steel roof racks, Gear wheels with bf Goodrich KO2, spare wheel on swing away mount, light package, leveling jacks, custom vinyl wrap.
As for your kayaks, the roof rack is custom steel rack. I had mine made shorter so it would fit into my garage with the roof top tent installed. They could probably fabricate it to side mount your kayaks.
BRX is a small manufacturer compared to the others but part of the process is going to their facility to custom order your trailer to your needs.
