Yes - room can be a problem. Our CT has a forward kitchen, leaving a long corridor from each side at the back end. This area can be accessed from inside, as can the side areas. These have limited storage area - but are still useful.
The main storage area for us is the floor of the trailer, which offers quite a bit of space. this area needs to be emptied once the CT is opened, but that is not a problem.
Luckily we have two large bins on the front which also help, even though the kitchen is located there as well.
Let me know if you would like some images.
Cheers
