I guess I need to understand the proper positioning for the COG over tandem axles as well as proper tongue weight.....
If you mean what the trailer should end up with, you want the COG of your cargo (camper + stuff in the storage areas) to be 10-15% ahead of the centerline between the 2 axles.
In other words, measure from the hitch coupler back to a place directly between the front and rear axles. Then go 10-15% of the way toward the front. That is where your trailer wants its load COG. Putting the camper COG right there will work but if you add cargo under the cabover, you'll want to move the camper back some to compensate.
When I checked my 16' cargo trailer in the past, I believe the deck was such that exactly half way from front to back was between 10-15% of the way forward. So if I load a perfect symmetric load it would end up with ideal tongue weight. This is why there is more deck in front of the axles then behind.
