Comparing an auto manufacturer to an RV manufacturer is really stretching it IMO. Robots build the majority of the vehicle and, every vehicle is inspected by a human Mark 1 eyeball to insure quality..
An RV has many more types of systems than a vehicle !2 VDC, 120 VAC, and inverter, charging system, Water both city and a pump, and more. While the vehicles 12v systems are much more complex, much of it is computer controlled and through the OBDC can tell you what is wrong.. (most times anyway). RV's are built by hand be workers that can have a bad day or miss an important step or a myriad of other issues. Have you ever looked at an Arctic Fox or other Northwoods product? Their quality is indeed built in and they insure it meets their standards on every rig built and if they had a rig with a design like the Key Largo, it would be a serious contender.
Go to the factories, tour the plants as we have and the difference is obvious.
I have been auto in assembly plants in Michigan, Ohio, Kentucky, Tenn., Miss., Va., Mexico, Italy, Brasil and Germany and have yet to see a vehicle put together by robot. Robots involved in welding, painting, lift devices. Humans doing the assembly. What plant is the majority assembled by robot? The inspection you speak of by eyeball is the worker doing the assembly, not a QA inspector. Again, what plant do they use QA to inspect EVERY vehicle by eye after it is assembled? Do they take sample cars off of the lines and check, yes, every car, no. My truck has a DC system and a 120 volt plug in too. I will give you the water pump, a very complicated system.
Yes, I have looked at Artic Fox, before the local dealer quit carring them for lack of sales. They are a good unit, quality above other brands, I didn't see it. In your previous post you said Northwood's QA was above the other plants, how? Because they had someone visible? I still stand by you can't inspect quality into any product, it has to be built in. And IMHO, auto manufaturing, any manufacturing is the same. You have systems in place to build a quality product the same every time, take the variables out that can cause a defective issue, and standardize you system so it is repeatable.
