Just to let others know, I passed on the Winner status, as I think @3Wliners needs someone who will give their test mat a more realistic work load compared to my current Pavement Princess uses. Good luck!

currently using the full bed rug, walls covered, shaped around cleats, etc, works well for keeping things from sliding and okay for knees. Had a drop in on a 3/4 chevy but it can cover cleats and attachment points, and now with Pro Power Onboard, openings are needed for that as well. Just the...
Hard to say, based on what I have tracked in my spreadsheet, look for Red font (link in my signature below) most multiple module failures are detected at the same time at the dealer. But there has been maybe a couple that had to go in a second time.
@Ford Motor Company wish there was an official detailed list of changes made for the various updates with a way to see the history of all these changes. Should also include information on how the app differs for each model / major component like Pro Power On Board. @TaxmanHog did you have PPOB...

SR has 4 Pouches in parallel per "cell", ER has 5 Pouches/Cell

Another point, to run something in the frunk while closed, my system said it would not work if over 175W.
I think someone came up with a timer controlled 200W heater that kicked on every 5 minutes for a few seconds to avoid PPO from shutting off due to an insufficient load...
