Bedrolls could ideally be crafted items. I mean there's pillows laying all over... some needle, some thread, some loose cloth, put in a pillow and voila... bedroll.
Ok fine. You throw out a bed roll. It only suits one person (same as the beds do unless they are larger) and then you click to lie on it. Now, as you are lying on it, it ticks up your health slowly like it does in the inns, etc...
Is that what you are asking for? If so, I honestly don't see a problem with that considering the numerous others healing sources there are in this game. It isn't like you being able to do that is an advantage and if you tied it to crafting, well... there you go.
So.. good point. I can agree.
