Hi Debra, I have been showing critters ranging from 14.1 to 16.3 in the same Country Carriages Road Cart with no derogatory comments. I have also been using the same vehicle for my tandem, the shaft horse being the aforementioned 16.3 hh (well ok, 16.2 1/2) warmblood. I think you should have no problem fitting something to both sizes you are contemplating. Not fancy, not totally correct, but I have been in the ribbons both in pleasure and CDE and I do use a wedge with it. I have pictures if any one wants to see it. Of course, my favorite tandem vehicle is the B-i-H Skeleton Gig. Nose bleeder, but oh so cool.
