My potti room works better for the wife than me for obvious reasons, but it was a must have. The toilet drops down into a 3/4" recess so it can not slide around, and the straps are for transport. Hate to have that thing bounce loose ! Though I have been amazed at how smooth this trailer rides. Stuff does not move around much at all. In my truck I had the thetford curve. This one is the Camco equivalent, though a little more stiff and void of some niceties the Thetford had. But the Thetford pumps go bad so quickly and this has a manual pump.
