New to the hybrid adventure

WE had an 2001 Bantam and the back bunk fit pretty tight in it as well. Must of been a design issue..

Thank you all for the insight to our dilemma. We'll see what we can make work as suggested.

On my old Starcraft pictured in profile I would fold mattress and store it against the doors with straps

I could turtle in it and use entire camper and sleep in the perpendicular bunk beds. I miss her greatly.

I had a 2004 StarCraft 21SSO which the same issue. There was not enough room between the bed bottom and the interior cabinets for the mattress to squeeze between. We always had to place the mattress elsewhere inside. Only the front had this issue. Rear bed folded up fine.

I believe my Bantam listed below is very similar. The back bed took some observation to find a best way. Not much space so we make sure the bunk end support frame is under the mattress and retaining straps are snapped. We then fold the canvas like an envelope is made. A 45 degree overlap seems to work. Check for bungee's that they are inside and fold it up. No room to leave bedding on matress. Hope this helps.
