Hi Edmo! We are considering the same. This past weekend we went to the RV & Boat show in Louisville, KY to see some options. And they had plenty; sadly most were over our price point.
PROs of the 30DS
Love the floorplan
Love the length for manouverability
Like the mid entry as opposed to the front entry of most diesels
Cons of the 30DS
Hate the noise
Hate the handling even with our improvements we still get a LOT of sway
Dislike the water issues we've had with this coach
Dislike the furnace/AC problems we've had with this coach
So our next stop is here:

I can't comment on the Thor as I have zero experience with them.
