As many said, your limitation is tongue weight. You need 13 to 15% of the FULLY LOADED TT weight on the tongue. Unloaded weight has little meaning. If you must use unloaded weight, assume you will be AT LEAST 1000# heavier when loaded. So if your Chevy has the 8500# tow limit (max in 2012 I think), then I'll bet the tongue weight limit on the Chevy (not the hitch, the vehicle) is 850# If so you max FULLY LOADED TT weight is 6500#!!!!!!!!!!!! Overloading is, IMHO, NOT safe.
According to the owners manual it is 1000lb tounge weight limit for either the 1/2 ton or the 3/4 ton with a W/D hitch.
However, the GVWR or rear axle rating will be the limiting factor due to tounge weight and stuff in the vehicle. They do need to consider the tounge weight as a % of the fully loaded trailer. 8000 lbs of trailer means a tounge weight of up to 1200 lbs if at 15%. All trailers are different so it is tought to estimate. If the % is high unloaded it will likely be high loaded. Also look to see where you will be adding weight in the trailer, where is the storage. They definitely need to keep the tounge weight down and a smaller trailer is the best way to do that. You don't want to play around trying to get the % down by making the tounge only 10% or less.
