Hello, I'm a recent Sprinter convert (sold my 2012 Ford F250 + Horton Hauler 16X7 Enclosed trailer) that I work with my hardwood flooring business. I bought my 2014 Cargo Crew 170 High in June, and simply love it. Since then, and with very little research, my curiosities are on fire with what everyone is doing to these vehicles. I need to access the metal roof and my van has factory interior panels. I understand the few plastic push pins, but there must be more, hidden clips inside. Does anyone have any insight on how and where to begin? I definitely need mid-van ceiling access to mount a Glee AC/Heater, as well as running the wires inside from a new Renogy solar panel set up that just arrived. I'm stoked, but am not interested in destroying what is in place and fairly decent. Thanks in advance for your helpful insight. And I have a million and one questions. Any hardwood flooring questions or advice is free and my 20+ years of experience is at your disposal. Thanks!
