This 35d is the first one this dealer has seen. I'm sure they still learning how to fill it. I'm being patient and not going on any long trips.

Either your SA is right and they haven't been filling yours properly or you have a massive leak. Using 4-5 gals of DEF in roughly 1,000 miles simply does not seem possible.
Does your paperwork show the number of gals for each DEF fill?
IMO All of us (35d owners) need to require that our dealer tell us how much DEF was used to refill the tanks. That is the only way we will be able to get a handle on the usage rates for the 35d. It pretty obvious that (at least some of) the dealers are clueless about this issue.
