I checked with Leitner Designs, based in Corona, CA, if they plan to make any accessories for the Grenadier and they replied back saying they plan to make a roof rack and Roo Guard. They said they will be available early 2024 but did not have specific dates or prices. The reply said they will put me on their email list for notification about availability. Might be a good idea to contact them so they know there is interest in this product and also to be put on their mail list. Contact info below.
