Yes. I removed both side panels, the tool kit access panel, and all plastic trays. I'm going to check the sunroof drains next, and do a water test.

There is some very light corrosion on the floor throughout, and I noticed some significant corrosion on an unused electrical connector near the floor on the right side beneath the fuse box. I recently replaced the 2nd stage brake light in the lift gate on that side due to water infiltration around the seal, but I don't think it's likely that water inside the lift gate could make its way back into the body.

Hopefully I'll get some time to do the water test this weekend, and I'll post pics and findings.
