My verbal search turned up that the difference between rv and rv lounge is the lounge is small, basically one room/space & has seating & small table that converts into bed for sleeping.
If the g'parents plus parents plus all 5 kids were sharing the 2 very small "houses" with only one bathroom, yikes. And

. Thats barely a step above homeless.
I'm wondering when in time they kidnapped and tried to force her oldest son to join them. Was it after they'd secured decent housing for them? Or when they were still being sheltered by her father & his wife who kindly inconvenienced themselves to accommodate them all? How would they have accommodated all 6 children even in the next place after Chris was thrown out?
It does seem these emotionally immature parents focused more on shiving their exes by USING their kids as weapons against than they focused on doing the best for their kids. I can't imagine any professional therapists approved of any of these collective actions.
The coming contempt hearing should be even more informative than the emergency hearing.
