Customer service lacking

Looks typical for dealer's length of service for those items. A good PDI would have found most of those items and then the dealer would have repaired them in one day in order to get your money. Manufacturers just placate consumers which is what they are doing. You do have a right to get a refund on that 5 year warranty, pro-rated of course (I did that years back). Good luck. My brother in law bought a $100,000 motorhome that went in for warranty repairs 35 times, many for the same motor problem. I finally advised him how to lemon law it and he is going through that now. He used it 6 days in a year! Good luck to you; I think you will need it because what you have described it normal dealer service. Hint: try getting the manufacturer to authorize a mobile rv repair guy!
