The typical RV is definitely not NASA quality.
Nothing but "NASA" is made of NASA quality. Military is a close second. I would assume privatized space travel (rockets and such) is in there somewhere.
Considering everything, I am impressed with the quality of a typical automobile including the Ford E-Series chassis. Unfortunately, only a rare few RV manufactures try to mimic a little of those practices, Phoenix being one of them. Considering such low production numbers, automation has no place at Phoenix. So it becones a carpenter's project with a plumber and electrician getting involved.
We had our house built for us in 1988. Being that they were building the house on property we already owned, I had full rein to inspect everything as it was being constructed. I was there every morning and evening before dark. Being the archetect, I wanted the crew to rely on my presence once a day in the A.M. to discuss any issues or concerns. In the evenings, I would do general inspections, certainly was never a critic, especially over frivilous things. I cleaned the work site on the weekends, did the painting, the staining and finishing of the wood-work, coax & phone wiring, duct-taped the exterior sheething foil backing seams and used expandable foam-insulation around all windows and doors. So at times there was some timing of effort involved.
One thing I learned about home construction....they are surely not building furniture. When it comes to the basics, the workmanship of a Phoenix Cruiser and a house is not so different. The main difference is that the house remains put, but all motorhomes live on a fault line that is extremely unstable on a regular basis. The plumbing of a PC is exceptional, just like a house. Regarding wiring, we use conduit in these parts for home construction so there is no comparison.
