Counter weight for added back storage area/deck

Perhaps it is my TT and TV combo but I have towed it heavily loaded with the fresh water tank full and enough stuff for a six weeks trip across the country; or a lightly loaded two week jaunt.

The only adjustment I make is a chain link or so to keep the TT level.

Others seem to have great difficulties with sway etc. I believe you simply have to load up and see what you combo does.
