Looking good. I have the yellow Back Rollers too.
I was also going to suggest that you use part of the empty front pannier for tools. There's no reason you have to fill the panniers to the top. And anyway, you will be surprised just how easy it is to fill all those bags.
If the air mattress came with any instructions, I would check how much air you're supposed to put in it. It looks really full in that photo.
