I'll probably get flamed for this but I know what you mean about Jayco. In previous RV shows they're units were of dismal quality. They couldn't even get the steps lined up under the doors. There were many other issues we found when looking at them too. They were clearly bottom of the line.
Fast forward to last weekend at the Seattle RV show where I was pleased to see that not only has Jayco improved tremendously, all brands seem to be doing a better job.
We were very happy to see some change finally coming to the industry.
