2007 Atwood would have electric & gas switches on one panel with a fault light
2007 Suburban would have gas with fault light & electric in the outside compartment (lower left corner)....COULD have an add'l electric switch inside IF RV MFG added one. If so it could be on range hood, face panel of kitchen cabinets, on the wall, with the gas one----just about anywhere and it would be in series with the outside OEM one (both have to be ON for electric to work) IF RV MFG added one!
