Refrigerator ventilation problem

[CBnOK]

Would like to find out if anyone else is having the same problem as we are. Purchased a new Silverback 29RE four weeks ago, the refrigerator has not operated properly since day one. Even took it back to the dealer for them to diagnose and fix. They got the Cedar Creek engineers involved, and came up with the solution of installing a second fan. Got it back home only to discover that it is still not working properly. The refrigerator is in a slide, so there is no roof vent, plus the factory installed the upper vent too low (per the Dometic instruction booklet). Anyway, after this long history, has anyone had this problem? If so, did you get it resolved and how? Any input would be greatly appreciated, we haven't even got to use it yet...so frustrating.
