We also use "all stays" and it has been a great help. Even in Canada. It has a data bank built in so it can still work even if you don't have internet access. It has several filters so you can select what you're looking for such as state parks, private parks, dump stations, even RV friendly Walmarts, truck stops etc. Best $10 bucks you'll ever spend.
I understand that the city water goes in under pressure and that the water in the fresh water tank needs to be pumped. Okay, why can't the city water on the way in (under pressure) fill the fresh water tank along the way just as the cold water, city or otherwise fills the hot water tank on the way?
