Warranty Work - How long is too long

Yes, sometimes things do take time, but my problem when I first bought my motorhome is there was a short list of like five things wrong. The most serious was the generator would start and then shut down after a minute. It turned out to just be a kinked cooling hose. The second most serious was the turn signals wouldn't flash. The third most serious is the wind sensor on the automatic awning was beeping which meant it was not working. I don't even remember the other items, but they were minor.

Took two weeks to fix the generator and they called me and told me the motorhome was ready to pick up. I went to the shop and got in it and turned on the turn signals and they still didn't work. The guy fixed the generator and didn't touch the other items on the list. So they have to order a new flasher unit and it takes a week and a half to get in. They call me and tell me it's ready to pick up. I go to pick it up and check the wind sensor on the awning and it's still beeping. The guy said he checked it and it worked fine. I asked if he had turned the switch on and he said what switch! So another week waiting for that part to come in. I'd call that human error!
