Thor or Forest River - Warranty and reputation

When I picked up my new Forest River in 2018 I was told "you are going to have issues. Go on a couple trips, write them down, then bring it back to get fixed." After a couple trips I had 7 issues I had documented. All were fixed under warranty and none of the 7 issues have re-occurred. This was the basic warranty. I rarely do any extended warranties as I think they are a waste.
