01-04' Tacoma frame replacememt

Hey there folks,
New member although not new to Toyota P/U's. Looking for some advice on my new/ used California born 04' Tacoma Xtra cab 4x4 w/ 110k miles. I noticed some rust on frame, then more, then more. Looked around on web and found out about frame recall etc...called Toyota and now have a case number/ appointment scheduled at a CA dealership. Has anyone in CA had a frame swap done? Positive experience? Where? I would like to start the process somewhere it has been done before so my chances for help in this case are best. Thanks everyone

 

Here are some photos of the frame (first two show where I sanded a bit to see the depth/ extent of the rust)
