How to hang a clothes bar across the back seat?

I also lost the rear over door hanger loops when I went to my Ram from my previous Ford. Luckily, I made due until I upgraded my camper and now have generous closet space for clothing. I tow an enclosed trailer most of the time and I rigged an internal clothesline for drying items that doubles for hanger hook locations. It still would be nice to get that hanging space back for bulky jackets or life vests when I don't have the enclosed trailer with me, so I am interested in what you find.
