Long time since I’ve done it but I think principle is the same-- arrive st frontier, go to customs with documents for truck and load, they may send you to agents to clear load at frontier or allow clearance inland. They’ll want kilometrage reading off truck too. You pay on exit when total distance is known. Assuming you’re on T forms and a max of 4 metres high? The Swiss Zoll I found quite helpful providing you weren’t there at peak hours.
