Update 25 Feb 2018: the tank is here and will be installed at Mercedes of Reno on March 1st.
I’ve paid as of today, waiting for shipment info on Feb 7.
Mercedes of Reno will be doing the install. Ask for Kwanny (service manager) if you also want an install. Please let him know that you heard about it at Lloyd Chambers' WindInMyFace.com.
