I’ll go out on a limb and say there’s more to this story….
I’m sorry you have to live in an RV as well. I’m sure the issues don’t help either.
Are part of your warranty “issues” the fact that you are living in it full time and unable to meet the dealers needs to bring your camper in and leave it there for repairs?
If so it’s a catch 22 for you as the dealer does not have to cater to your personal situation and this may be a convenient out for them.
And you may be overusing some of the features of a low end trailer.
Also to consider in the future , never buy a brand new RV unless buying it as a luxury.
