I have a 2012 north trail 32qbss and was looking into installing a ladder on the back to access the roof. I have searched and found nothing on this. Anyone have the same model with a ladder on the rear? I have called a tech at Heartland and got nowhere. I am looking to buy the la401 universal ladder. Is there any places to mount the brackets on the back of the trailer? Any help would be greatly appreciated. Thanks.
