Just off the top of my head, a big Ikea carry bag with a waterproof dayglo and reflective jacket just in case, a 5ltr plastic chemical bottle full of screen wash, (the Octy takes 5 litres at a time), a blanket, and a couple of those big blanket things that removals people use to protect stuff, to cover the boot area when carrying a bike, a new Aldi sleeping bag in its bag, a couple of walking sticks I’ve made, for when I’m out walking on slippy ground, my Muckboots, an electric air pump for air mattresses, and a little case thing with spare bulbs, fuses, a few tools, and a nine-ton orange webbing tow-rope. Just in case, had it for years, not needed it yet.
