Our support poles under the bunk ends do not offer enough support. After one night of 2 adults sleeping on the queen side, one bracket completely pulled out of the bunk. the other is severly bent. Would longer poles and a wider span be an option? What have you used to support the beds? Btw...it's a 2008 Skamper. Where do I get new brackets? What are they called, so I know what to search?
