Thanks all.
This is a photo from a brief test in the back garden just to make sure I know how to put all this stuff together before I have to use it. I'm going to try it out tomorrow night somewhere in the peaks. I hope my new sleeping bags nice and warm!!
Everything packs up MUCH smaller than before. I've managed to fit everything in the bag on my trailer. Whereas before I couldn't get the sleeping bag or mat in there so I had to strap them to the handlebars of the bike / on the top of the trailer.
I'm almost tempted to try pulling the trailer with the fixie tomorrow, (I was planning to fit lower single speed gears before I attempted to pull the trailer with it).
