@Yannich Captain I've watched good installers. Ideally, the company would have it's own installers, but that task is frequently contracted out. The installation of any equipment can be done improperly, but with what we do, we can FEEL the errors, often immediately. EVERY installation WILL have problems. They were transported on a rolling earthquake. Good installers know the problems to expect. Good installers are well prepared, and over prepared (extra stickers, weight pins, etc). Good installers are there for MANY hours after the equipment has been setup and installed. The more equipment, the more hours. I'm guessing you mean an equipment setup and installation manual with instructions. I didn't see Thor Swanson using one, but he wouldn't need one.
