Testing mounting the 1up racks vertically to the Sherpa. So far I really like this setup. Super easy to load/unload the bikes. We are adding straps and possibly a lockout bar for the bottom arm. Outside of that the 1ups bolt right up. Best of all they close totally flat when not in use 🚐 🚲 #owlvans #1up #sprinterbikerack #sprintersherpa #sherpa sprinter4x4 #ibisripley
