Actually you really don't have an excess of problems! I'd guess this is your first RV, right? Unfortunately, RV's are more like US made cars of the 70's, and not like the cars we buy today. After owning 12 different new RV's over the past 25 years, I can say that typically it takes 6 months on trailers and a year on motorhomes to get them "sorted out".
Just chill a bit, get the things fixed under warranty and enjoy your RV!!!!
