Probably not what you want to hear, but Thor has a pretty checkered reputation in the product quality and after-sale service areas.
That said, welcome to RVF. We are a friendly group with lots of collective RV experience and we will try our best to give you solid answers to questions, even if they aren't always what you would like to hear.
This may not be what you want to hear, but I suggest staying far away from Thor.
A close friend bought a 2019 Thor...owned it for 18 months....spent 12 months at the Dealer! He's very upset with Thor, their significant product issues, coupled with a poor performing Dealer doing the work!
You may be better served to look at other manufacturers!
