Good info so far.
I would definitely add that you can mail order your swiss and austrian vignettes online ahead of time. Definitely worth while and takes away some of the stress (finding a gas station or stopping when you are short on time)
I'm sure this is a minor detail, but I'm pretty sure you don't need a vignette if you aren't planning to use the highways. When I looked it up, it was only required for highway use. My Austrian vignette was a waste of $$ on my ED.
The only reason why I mention this is that Munich -> Grossglockner does not require you to use Austrian highways. In fact, I never set rubber upon an Austrian highway my entire ED.
For example, we bought an Austrian vignette
