exact total length of 04 crescendo 8386

New to forum, and have been learning a lot about the Gulf Stream units. My question is looking at buying used 04 crescendo 8386. Went to manufacture site and it states 38' 8" as overall length. Have an existing shop that is 39' from door slide to wall. Can someone actually measure theirs for me? And answer the question does that overall length include the ladder. I want to make if fit, but if it won't will look at the 36' model.

Thx for any reponses
