Do you really need fixed beds?

DaveT

Assuming that there are only two occupants in the caravan and they are happy to have single beds - do you really need fixed beds? With the advent of the raskelf duvalay, the old problem of using sleeping bags (tying your feet up in knots) seems to have disappeared.
If its only a case of un-rolling the duvalay and throwing it on the bench, then the issue of making up beds seems to have gone away. Does anyone use a duvaly in the coventional twin bench/twin bench side dinette layout? Appreciate your thoughts.
