Our dealership is flexible.
Sometimes they'll just give us an item (like a piece of trim) knowing I'll install and they'll run the paperwork as completed warranty work.
I pulled the furnace and brought to them for repair.
For larger items we schedule a vacation. Something good you can do that's non-RV (Hawaii for a week?) and drop the trailer off on the way out of town.
Looks like we're pretty close to your location
