My hubby and I have 2020 Terrains, but I bet the same would work for you. We both use the vertical cargo net - clips onto the rear hooks fine. This is the Terrain, I’m sure something similar can be had for an Arcadia. https://www.amazon.com/gp/product/B07FKTYC8V/ref=ppx_yo_dt_b_asin_title_o07_s01?ie=UTF8&psc=1 We also have cargo containers that expand out - but fold up and can be stowed under the hatch when not needed. https://www.amazon.com/TRUNKCRATEPRO-Compartments-Collapsible-Organizer-Recommended/dp/B07CZMDFFW. We have cargo mats in the back that prevents the cargo containers from ‘sticking’ to the carpet floor mats, but they can be latched down with the straps. No issue. We love them. Just hauled two propane gas tanks to be refilled in these no problem.
