Swapped out the Slinky mediums from
@dockbox (Endless Horizon Outfitters) for the heavies tonight. Great customer service and fast shipping.
They feel great. I think it's going to be the perfect setup for bumper+spare tire+gas cans+2-300 lbs of gear. The ride is just as good as the mediums.
Took my rake from a little under an inch difference rear to front, to 2 inches. Stink buggin a little, but it's better than sagging under load.
After, Slinky heavies, unloaded cargo area with Slee rear bumper and spare tire:
