Is such a low cargo carrying capacity possible?

Our last TT had lots and lots of storage space and a CCC of 888, which was abysmally low for long trips; I have no doubt we overloaded it from time to time, as we did take trips in it that lasted 5 weeks or more. If you're not planning on long trips, or living in the trailer, and if you are very careful how much you load into it, you can make it work. But if you are leery of that low a capacity, you may want to move on and consider another unit.
