I am doing lot of camping these days with my rav4 2021. I convert back seat and cargo area a one big sleepig space. I have rooftop cargo which frees huge amount of space. But still, i have lot cluttering around bed area. It will be nice if i can free up some more space. One idea is cargo cover bar with extensible fabric cover can hold some stuff but not much. I am wondering if there are more solid material solution such that i can put more stuff during sleep "OVER" or "ON" the cargo cover not below it. Any?
