For those with no bathroom access during travel mode.

We make do with the 5er without potty and sleeping access OK. If I absolutely have to have access, I can take the bathroom door off the hinges (really easy) and can squeeze in, then access to the bed through the 2nd sliding bathroom door. The fridge has access if I remove the parrot cage from its travel position. Been using it this way for over 8 years. Where there is a will there is a way to make do.
