Hey people, This idea is so simple that I am sure it is known to most...but what the Hell? Here goes. On a recent 2000 K trip down South I made up a piece of dowell... About three quarter inch diameter. I sewed a piece of one webbing around the centre of this dowell and then, about four inches from the dowell I sewed a one and a half inch S/S ring.
You position the dowell inside your car door and shut the door. This leaves you with a suspension ring hanging from your car exactly where you would like it to be. Now you just park the desired distance from any vertical object and you are home for the night.
It worked fine. Make up two and keep 'em in the glove box. You will never need to sleep on the ground again.
