The International dealer had none, backordered.
The isspro one's probe doesn't seem too eager to move, and I don't want to break it, so it'll stay on the RV.
I ordered a $250 (w/tax) Autometer gauge to be delivered to O'Reilly's there where I'm picking up the van, so if i can't get the Banks one working, I'll have a new one to put on before i head back.
If i get the Banks one working, it can be returned unopened.
And if i need it, i could later order another "ship to home" one for less money (with a promo code) and return it to O'Reilly's on the higher priced receipt.... they might not like it but...
