The biggest problem is actually the front crossmember. Once you get it laying frame from front to back then you only need like a 1.5" body drop(don't remember exactly how much) to get it to lay rocker.
But this also seems to be somewhat of an anomaly some guys claim they have to z the front and some don't.
A 2" traditional body drop was pretty easy to achieve, nothing really got in the way, but when I tried to get another 1.5" all kinds of stuff started hitting. Then your headroom is really limited.
Also though I never really measured for laying rocker, I am working on laying door.
