Thanks for the prompt reply's,
JK we are having a porta potty placed on the draw bar, it sits inside the rectangular tray and i guess its strapped down? didn't want it on top of the camper or inside the car. Use the bush most times, but in WA more and more sites require you to have a portable toilet or no entry.
Thanks for the photo, yes that box, often wondered what was inside it.
Thanks tjwrexy for the photo of the legs, i dont know what our new camper will have but these seem like a great idea.
Still waiting for a delivery date of our new camper. Will put up new photos as i get them
