I've never understood swags INSIDE a camper...
what am I missing here 
From my point of view mate, it serves a number purposes,
1. easy to sort out, just roll it out,
2. easy to pack up, just roll it up,
3. warm bedding when in colder months,
4. when in hotter months just sleep on top if needed,
5. if space is a premium you can carry them on the car when req,
6. when I have a boys weekend, I just throw the boys swag on the roof of my truck and off we go, when my daughter gets a bit older ill do the same with her.
We went thru the whole beding stuff when we got back into off road camping, and the swags were just so simple for our setup, and also gives us an option when, like I say I head off with the boy by myself.
Its not the best solution, but its the best for us.
Hope this gives you some insight mate.
