There 2 complete different animals.
The 28 excel does not have the freeboard a 29 does.
The hull design is completely different. The 29 is a more solid ride and doesn't beat you up like a 28 would due to the bottom design. I know, I have ridden in both and own a 29.
The cabin height is higher, with more room.
I would say if possible, ride in both of them. I know the dry weight of a 29 is 5500lbs.
I'm sure you will get somemore input on this from the other guys. Godd luck with your research.
