I owned a 232 and a 25 outlaw... If I recall correctly, both had a huge acces panel in the floor... Why in the world would a 275's floor would'nt have one? What happens if fuel thank or stringers needs repair???

On the 272, the floor is removeable. It's about 3 feet wide, and extends to the back seat area.

You're saying the 275 is different?

Pretty sure yes. Anybody else can confirm?
