LM and BH are manufactured on the same line.
The two items I missed in my PDI:
1. Calking, very poorly done. The side strip between the lower wall and upper wall had cracked caulking which caused the metal screws to rust and snap. Unit goes in next month and all caulking will be checked and redone (on their dime or mine, but it will be redone) along with the required fix.
2. Slide alignment, both rear slides on either side are miss-aligned this caused the fascia to pop off around the entertainment center. One side doesn't even close tight to the weather stip. So close the slides and stick your fingers in around the slide and look for gaps. I made sure the slides worked during PDI not that they were aligned, who knew.
edit couple more things:
3. Convenience center. Pull the wall and make sure you don't have leaks behind the center, leave the water pressure on for as long as possible. We had 3 bad connections.They repaired one during PDI. The other two I did later.
4. BAL spare tire carrier, triple check this. The drivers side part that connects to the frame came out and disappeared on i90 within 1000 miles dragging the carrier and tire under the rig for some time. Nothing damaged but the carrier thankfully.
