We purchased a 2018 Thor Freedom Elite FE a month ago from an owner who did not have any of the original Manuel’s. We live in a semi remote area so have spent time trying to locate information about our “new” RV with the Mercedes chassis. Our problem at this moment is that the chassis battery is completely dead. Where is it located? We know that the cabin battery is under the entry steps, but are not sure where to find the one for the chassis. New RV ownership is not for sissies!!!
