I've been looking around but I can't find anything online... Does anyone know what the holding capacity is for the factory automatic running boards? I have a 24 Rebel with these and I have a road trip coming up with a couple brothers-in-law that tip the scales at just around 450 each. Can my running boards take this stress or should I just keep them stowed for the trip? Thanks in advance for any answers (helpful or otherwise lol)!
