We are using zen cart 1.5.4. We already use the numinex fedex ground/express module but need a separate fedex freight module with the following features:
Display negotiated rates.
Allow for pallet weight added to total weight. Editable weight in admin.
Allow for handling fee (included in freight estimate). This field needs to be editable in admin.
Force freight only shipping for order weight above a preset (and editable in admin) value- such as 101 pounds.
Set freight class (editable in admin). Default to class 85.
Test and confirm that negotiated rates are being displayed.
