Welcome to the forum.
As the others have stated, Slide depths can vary. A living room and opposing bedroom could add an additional 70+ in.
Entertainment Hatches and awnings can be in addition to that.
Some retracted items like awnings hand rails, fixtures etc. can make the trailer slightly more than 100" also. Basement hatches require nearly 3' of clearance to open on ea. side also.
