The best Truck for a Host Mammouth

I understand that the prices at the moment very high. We want to start out tour in 2 weeks , so we must buy something.
I have 2-3 trucks in this price range, most of them silverados, I like the Silverado.
I don’t think that European are the better buyer here, it isn’t easy for us to understand the Prozess of negotiations, There are a lot of difference opposite Germany
