Emergency fire escape windows need to be kept clear, so as not to hinder your egress in an emergency situation. If the furnishings prevent the window(s) marked EXIT from being opened or used, you have a valid life hazard. I would call FR about the problem. Our sofa back sits under a egress window...but it doesn't hinder it's use...I tried it on day one.
Are the furnishings original equipment, and are they placed where intended by the manufacturer?
Sometimes previous owners change or move them. You may need to send them some pics. Rv safety codes will vary somewhat from buildings...so I can't say for sure if they violated code or not. Either way...It will put you and your family in jeopardy during any emergency.
Good luck, and please post your results.
