I’ve added 3 rain fly holders that fit and work really well. I’ve just added a double fist grip setup for my shovel and Rogue 55HX Beast with 40" handle.
Headed to the desert to test. Feels solid. I don’t expect any issues.
Note: at least on my V1 XL, make sure you align the flat back parallel with the panel. I could see someone really putting a dent in it.
