So on this last trip out dtr and her boyfriend slept on the front bunk. The were cuddled out towards the far end of the bed, and the bunk end was majorly sagging. I put the auxiliary support that came with the pup (it has had this problem before I owned it) and that helped some. Then when taking the pup down I noticed that the roof of the pup did not meet the bottom portion, the bottom portion is bowed out. I think the supports put too much pressure on the front of the pup and bowed it out. To top it off I did not have the bunk end slid out all the way, and it only sags on the end that was pushed out all the way.
