First post, normally just lurk.
lots of tips, lots I've used while camping. Here is one that was not mentioned.
Old inner tubes make great hoses. Just cut it in half somewhere (near the puncture if it has one) and stretch the end over any water tap / spigot. Sure it's only about six and a half feet long but it's works. Best if you have a zip strap or extra hand to hold it onto the spigot. Then just pinch the other end where the water comes out to adjust the pressure. It's nice to give your bike a quick wash, or yourself a shower.
