Anyone replace inner rocker cab panels?

[Ftruck Fan]

I am wondering how big of an undertaking it would be to replace/section the rockers?

How much needs to be done?
mine, just this front section need work..bottom looks like swiss cheese..
If rotted at center were cab support intersects, pretty easy spot

I patched one small area of my inner rocker, and replaced the section at the front. Here is the small patch I had to do, it was underneath the cab floor support.

Here is the end of the rocker I had to replace. Also had to make a bracket for the bottom fender nut.
