I'm going to go a bit contrary on the OP's original statement. We bought a 2016 Winnebago Journey 40R one year ago. We are pleased with the overall quality of the assembly considering the complexity of the onboard systems.
Here is a list of the issues we had with the motorhome:
1. First night out the mother board on the back furnace failed. Not Winnebago's fault. Paid for by Suburban to a mobile tech.
2. Keyless door lock failed. Everybody's fault. We should have caught it in PDI. I trouble shot the issue with help of Winnebago. Problem was that the wires on the door frame side were not properly crimped on the assembly line. I fixed at no cost.
3. Master bath door latch died requiring some "work" to open door. Latch replaced by picking up part at Winnebago dealer. Fault of supplier not Winnebago.
4. Half bath door would not stay shut in transit. Fault of Winnebago because bath wall was miss framed. I fixed by shimming the door.
5. Glass insert in one cabinet door broke. Fault of Winnebago because nail holding inside trim in was too close to glass. Winnebago shipped new cabinet door to a dealer and I replaced it.
6. Had a water leak behind master sink. Fault of Winnebago for not tightening fitting. Fixed it myself.
7. Puddle on dash after heavy rains. Fault of Winnebago for bad seal. Fixed myself.
8. Matrix switch lost it's mind. Called supplier's support and figured it out. Not an uncommon problem. Fault of Winnebago for using this supplier.
9. Numerous loose screws, etc. Fault of Winnebago. Fixed them myself.
Conclusion, don't buy an RV unless you have a brain and a toolbox. I would buy another Winnebago.
