Thanks for your input.I watched a factory tour of heartland Big Country on you tube and it didn't leave me with a good impression.It looked like everything was rushed with little time for quality.I guess seeing it in person may make a difference.
When I was on the tour, I thought the people hustled around but also seemed to take the time needed to complete the task. Two or three people I saw applying decals really seemed to be doing a good job even though they worked quickly, They stepped back and took a look every time and adjustment before making the decal position permanent. For the holes cut for various switches and such, templates were used and quickly cut-out not because they were being quick and careless but because the templates can speed up the time necessary for layout and precise placement of holes etc. making repetitive steps much faster and easier. Of course, You can always try to find a company that will slow down and take more time for building a custom RV but I am sure you will find the cost increases significantly but may not necessarily be of better quality.
A few years ago, I took a tour of a plant that builds manufactured/modular homes (full wood frame) They seemed to use similar general construction methods as those I saw at heartland. Even watching construction on stick built on-site homes using traditional construction, The workers seem to move pretty quickly around, too.
Even the whole promotion/idea of using Amish workers in factory built furniture/cabinets is pretty hokey considering that, Yes, they may beAmish, but they certainly not using traditional Amish construction techniques that one might find in a Amish workshop. The heat surge Amish cabinet scam comes to mind.

Now, Real true Amish-built furniture in a true Amish furniture work shop really is usually really high quality, but when it comes to RVs or anything else mass-production built, you have to really question what are you buying when it says Amish-Built.
