I don't even own a Sienna and probably never will, but I still want to see what you've done. It'll be great if you've found a good way to make the Sienna into a credible overlander, since it has a huge number of positives about it.I just lifted mine and got a factory look with beefier rubber and 2-3" of lift with 12" clearance under my rear hitch. Works great and looks awesome. Let me know if you want more info.
