I ended up starting from scratch with the Equalizer set up I got from the dealer. If you didn't see the thread, here is the link http://www.jaycoowners.com/forums/sh...ad.php?t=20871
I downloaded the instruction sheet from Equalizer's website (because my dealer failed to pass them along to me) and followed them step by step. The difference between the 6K and 10K is a different hitch head and slightly larger spring bars. So, it will require you to take the hitch ball off of the original head and switch it to the new one. You will need a torque wrench capable of about 430 foot lbs. I called in a favor to get the ball changed. The rest of the set up was fairly easy and took my brother and I about an hour or two to complete. Just follow equalizer's instructions and you will be fine.
If you already have the 6K and it's working for you, I don't think I would bother to change it. It's not worth the expense of a new hitch if you already have good weight distribution.
