My hitch is a Reese dual cam. When the dealer installed they said to use link 6. On my last trip I went up a link to link 7 (tighter, counting from the end up) and had much improved results. After a trip to the scale I'd like to get another 20KGS off my rear axle, I'm not sure if it's as simple as tightening one more link?, or will the cams have to be adjusted as well. Is there such a thing as too tight? If I go up to link 8 I'd only have about 2 chain links left, and my bars would be quite a bit higher than parallel I'm also thinking my ball height may have to be adjusted if I tighten the weight distribution.
Of course I'll shift some weight around inside the trailer as well, just want to make sure I'm getting the full use out of my hitch.
Really I'd love to pay an expert shop to precision adjust this for me as my tow vehicle and trailer will pretty much always have the same contents.
As for the stump, that's awesome if it works out. I have some pretty specific measurements as I need it to fit in a plastic bin I use. Was wondering if there is a place you could go to 'shop' for these

Maybe yours is the right size! I'm pretty disappointed I brought it with me as I didn't even need it in the states!
