A quick question
When plugged into shore power, if you turn on the generator, which has priority. ?
And so i have to nessesarily unplug shore power before starting the generator?

It depends on the year of the coach. Let me quickly search for that info
ETA - several posts indicate through 1994 it was generator, post it is shore. Always check your build's schematics, though, and if someone replaced the main transfer switch you will need to safely open it up and check to see how it's wired.
And from the wiki/Foretravel Manuals media section on Electrical Systems

It is ALWAYS recommended to unplug before starting the generator (and to shut down the generator before plugging in) to minimize arcing/damage to the transfer switch contacts.

Peter,
It could be wired either way. Our coach is wired now as shore power is priority. I know of some that generator is priority, so like Michelle said it depends on the coach. As best practice I always shut off shore power and open main breaker before starting generator just in case the transfer switch fails. Doing this also keeps the transfer switch from swapping under a load causing arcing the contacts.

Well M got to the post first
