I don't think people are talking down to you but more trying to offer advice so you have a nice/safe rig. As far as no one else building something like yours on here, may not be a VX but I'm sure a few of us have had our fair share of in-depth builds with full on fabrication/modifications involved. But we won't get into that, but yes like Zeus said, it was just us making sure you don't get screwed. Saying he's a friend is different than us thinking it's some shop that promised you stuff and hasn't delivered. You just called him the "builders" and said stuff like:
"Sadly, the VX is back at the builders. I uncovered a few areas where they did not double check their work. "
We're just looking out for ya, it's an awesome build for sure and once everything is "done" it'll be one sick rig. Don't get pissed at us though for trying to help, this is a "tech" forum after all.
