Bunk bed need adjusting

[Less is More]

I just got my 2017 Rockwood Mini lite home and noticed that the upper bunk bed touches the wall at the foot end and is about 1.5 inches from the wall at the head end. Before I lug this back to the dealer, I was wondering if moving it would be a task I could undertake. Before I take the screws out, I would like to know if anyone has had the bunk out and can tell me what it would take to move it .75 inches.

Thanks in advance
