it is packed to capacity with as much as will go in it and still roll closed well. i knew i would take the main bag off for the trail ride and leave it at camp. of course with better packing discipline you could take less gear and it would pack lower more like a GL. i did have plenty of seat.
in addition, the tent is up high in the back like that because i burnt a hole on the exhaust in my other tent putting it down low on the fender. i put that down to my own error. i will put a rack and another heat shield on the muffler to prevent that in the future.
on another note, i tested the waterproofness quite well. the bag sat in the rain for 4 hours while i was at work and also experienced a 15 minute episode of pouring rain while riding and everything stayed dry of course.
