I’m pretty sure that front bump is maxx air roof vent cover, like this. Not a satellite receiver. https://www.campingworld.com/maxxair-i-original-roof-vent-cover-translucent-white-1733.html?gclid=CjwKCAiA25v_BRBNEiwAZb4-ZWEaiND7DmFYJmORCA1I55bGb6Yk9YjX9PZK_OSfyHNpTfrDJrYndBoCnK0QAvD_BwE&gclsrc=aw.ds Next is obviously ac, then the TV antenna, and another roof vent cover. This all looks like standard equipment, not special additional equipment or anything like that. Here’s another view of the inside of a Chateau showing an obvious roof vent above the front bunk. This is pretty standard. That’s definitely a roof vent cover, not a satellite dish.
