Tapping collective wisdom

DW is not too happy with the TM, hard to get into bed, more storage, bigger fridge. You know the list. So it looks like we maybe trading campers in the next two years or so.

Now the question. Does anyone know of a reason why I could not have the trailer built with a TM style Terlet but have it dump into the standard blackwater tank? The one I looking at has a 40 gal. tank and dumping 6 gals. only once evey two or three days and a generator that sure would extend boondocking time.

Sound like a workable plan?
