Have you searched through the My Camper Trailer Section, I thing there are a few rear fold MDC's listed where different folk have shown theirs. I do know of 1 that wasn't the outcome the owner had hoped for (The camper broke), this thread got locked I think.
The 1st reply above refers to how sometimes these questions can get out of hand when it comes to an imported type product.
For me, to answer your question, I have no experience with the hard floors, have had some with side fold soft floor.
Perhaps you should just go have a look at 1, if you not up for checking it over thoroughly, take someone with you who can and then decide if it is suitable for what camping you have in mind.
Looking at a 2nd hand one which has seen some use should show any concerns I would think.
