T880KW

So my exercise in frustration registering in Georgia has begun. We purchased a used T880, to be registered and used solely as an RV. 5th wheel removed, personal use car deck/ramp on the back. Our local tag office quickly directed me to the Atlanta office. The Atlanta office told me that the county office would handle this. The truck meets all of the RV requirements- Is there a magic inspection form? or has anyone had personal experience with a field agent/office that used logic to solve this puzzle? Thanks!!
