Haha me too mate :) the D38 holds a lot more than I was expecting, I managed to get all of my camping gear into it with plenty of room left over for water/food as well. The small bag will be more than large enough for clothing and essentials etc. so should be the perfect combination. The test will come on the weekend when I get the chance to try mounting it on the pillion seat of my Sertao with the BMW top box taking up the rack space.
Pics and a full review will come next week.
