Black Tank Valve/Discharge Under Coach Rather Than In A Bay?

Every Class C I've seen (including mine) have this arrangement, the only RV's I've seen with the dump in a Bay, are Class A's, I suppose there may be others.
As far as boondocking, this is the very reason I don't do it, fear of ripping something off, dump valve, main exhaust tail pipe, Generator exhaust pipe, at 9 1/2 inches of ground clearance, and a few other low hanging items.
