like somebody else said, if the loop is just on the hatch instead of on the body, there'd be a spot to hook onto lol. like on most hoods that I've seen, where the receiver is fixed and the hook is on the moving part.
but yeah agreed on the truck not being necessary. I've hauled a lot of stuff in smaller cars than this, and safely. I wouldn't drive this on the highway, but 15 minutes home on busy (so not high speed) stroads and residential streets? absolutely. this was an unusual load (typically I either have the hatch closed or use the trailer, been quite a while since I needed to have the hatch open tbh, many vehicles ago), but it was still perfectly fine. I made sure to say the incantation and perform the accompanying gesture before I left.
