I hope this is the place to put this information.
Since RVUpgrades.com is the sponsor of this thread, and hoping they read it, I would like to thank them for the help they gave me in acquiring my PT50C surge suppressor from Progressive Industries.
I order it from RVUpgrades.com and received an email that it was on back order but expected in within a few days. I emailed back that it was imperative that I receive it on or before a certain date. Another reply confirmed that I would, and subsequent emails informed me of shipping and tracking numbers. And the price was very right.
