Sorry I can't answer your question but I do want to welcome you to iRV2. My DW is in charge of the inside and I am in charge of the outside. When we get on rough roads I still hear a lot of rattles. She tells me she has done the best she can. I am smart enough not to question that.
Occasionally I hear some outside rattles. I blame it on the slide covers and the patio awning. She wisely accepts my answer also.
