Tiffin Allegro RED 38KA mattress size
Main bed72 × 80 inRV king
That's an RV king, 4 in narrower than a regular king (76 × 80 in). A regular king won't fit, so get an RV king in exactly 72 × 80 in.

Bunk mattresses in 32 × 74 in
Some bunks have a rounded corner, so trace yours before a custom cut. A thicker bunk mattress takes headroom from the bunk above.
