Warranty Work - How long is too long

I've been waiting a year still nothing done. MI Ridge don't work, oven don't work, awning was suppose to be replaced before deliveet , still nothing! Mine was taken to dealer, they told me 2 days is all they needed and it would be dobe. It was dropped kff, 23 days later I got it back (I live in mine) nothing was done it at all! I slept in my car, got hotel rooms and an Air BNB in the 23 days, it was expensive and I only planned  on 2 days. When they brought it back it was infested with maggots, they never plugged it in like they said they would! My freezer and fridge was full, the smell was so bad we could smell it before it waa even parked, as it got close we could smell it! My fridge us ruied, the smel! Will not go away, maggots invested the while camper and keep coming back. Larve everywherle! The cost of the continuous cleaning, laundry, replacing the food, hotels etc. Is well into the thousands. But they didn't do one thing to it when they had it! It still stinks and I don't even likeit anymore!
