Allocations are given based upon the sales volume for the specific model line. A high volume truck dealer that only completes 1 camaro sale a month isn't going to get a high allocation. I would recommend you look for a dealership which shows they have 10 - 15 stocked or in transit orders. I had the same problem and moved my order to a local dealer that has number of 22 and 23 units on the ground or in-transit. It only took me 30 days to receive an allocation.
