It's odd, on the GX550 and the tacoma it's exactly where it should be: near the rear hatch, easily accessible. On the Trailhunter, even without drawers you would have to unload cargo and crawl into the cargo area to work the compressor!
We have a solution! We've been able to work through the mounting/anchoring for our 6th gen 4Runner systems

Thanks for the kind words! We're just now getting onto this forum. We do indeed have a system for both the Hybrid and Non-Hybrid 6th gen 4Runners!

Perhaps we can be of assistance: Our system preserves your second row and allows you to have a sleeping platform when needed, while storing all your gear in the drawers themselves!
We will need to confirm the access, but we will make sure our system allows access to the air compressor. That compressor interface is in about.....the worst possible location it can be.... but we will make sure we provide access.
