Truck looks good Chris. Good job
Steering isn't bad at all, but it is different.
As far as the performance between an ADD setup and manual hub setup goes, there is no difference. As far as CRAWL trails go - if you do get a wheel off the ground, it will act like an open diff. A bit of action on the brake will get it to lock up. It doesn't take much, but it can be a handfull (or footfull) with three pedals.
It is not a replacement for a locker, which would be ideal for crawling, but it does offer an improvement over an open differential without any clunky operation or delicate parts.
One thing that comes to mind with ADD is that I am not sure if the latest differential is compatible. I know they were testing one a while back, and that the latest is supposed to cover more applications than before, but you will have to get the official word from Eaton. The difference is that with an ADD differential, you are supposed to have a needle bearing that supports the stub shaft on the passenger side of the diff. Mine does not have that, but was run in the past with ADD on the last truck it was on. No harm done, but I can't guarantee that it would NEVER be an issue. Right now I'm running the ADD tube with manual hubs, but keep the ADD locked full time. So far so good.
