I have to mention this. A cover for your RTT. No more packing away a wet tent after rain. Reflects heat. Keeps the inside dark on early sunny mornings. No bird crap etc damage. Stops sun damage to canvas during the day and best of all you can leave it on the tent when you pack it away. Looks a bit like lunar module when fitted though! We bought one and never took it off!
Only available at TuffTrek UK. They designed it. Others will copy it in the future i think. Great bit of kit.
