Vanleigh frame question

I've seen these apologists on Lippert supplied frames with these type of questions. The RV manufacturer gives Lippert the specifications and presto-changeo, frames start showing up at the RV manufacturers plant. Any issues with the frame is not because of the anything the RV Manufacturer has done wrong. Well I highly doubt that Lippert is just willy-nilly supplying frames based on an purchase order from the RV manufacturer. There's something called Product Liability and as Lippert has to warranty the frame, I'm positive that Lippert is very involved making sure the frame so requested will support the box being bolted onto it. Now how that frame is welded together and the experience level of said Lippert employees is another matter.
