Welcome, this is actually quite simple to me
but first; what did you mean by this statement
"Have had to park it 32 miles from my residence because of the rest of you needing the same." ?
What I would d if I were you in order.
1. Stop being angry (you need someone else (Thor /Dealers) to help you so smile, you will get better help from Thor or others you need to deal with)
2. Do not be frustrated. The fact that may be able to pay for parts out of pocket is not the point; don't pay repairs out of pocket, allow the warranty process to play out. But you will pay otherwise so pay for what is needed and don't complain.
3. Make a list of everything that is wrong. Drop the editorials on the list, just simple list of issues and defects.
4. Call your dealers and tell them what you have, asking when you can bring it in to get these items fixed.
5. I know it is cross state, but your money is best spent to get it back there. Be prepared to leave it and and go home. (don't be mad...
)
6. When they call you and say it is ready, confirm all of the items on your list before going back. Schedule the pick up where you can stay another night or two in that RV park that you like so well.
7. Drive you brand new 2021 Thor home in peace. If your coach was new, I don't follow why the need for oil change?
