Summit still does not have the tank in stock, they are still working things out with spectra i can only guess. Salesman told me the PN's don't bring up anything. I told y'all dont hold me to that date. Tom, i talked with RA about stocking it, they told me that even with that part number, there was nothing they could do with it, since the tank is not widely available. I'm guessing you just talked to customer service, or did you actually speak with someone in their purchasing department?
