Both my wife & I each bought an Expand5. We also happen to be considering a new mid-sized SUV, and would like any feedback on which ones work well, or don't work well to transport these folded inside instead of a hitch-mounted rack. I have seen mention of using a 70 gal tote bin, which look bigger than expected. I'm not sure many of the SUVs will fit two of these inside, even with the rear seats down. Any recommendations? Thanks!
