I have a fairly large trunk bag now and it works ok. Papers fit in it folded in half, but I rarely carry any paper back and forth anymore. It has light nylon zip-out panniers on the sides if I need them. If I roll pants or a shirt up into a tube I have to slightly scrunch them in there, but they actually still come out ok. However I use a backpack if I am carrying my laptop because I think the trunk bag might give it more jolts.
