my Roo doesn't have the pre-attached canvas and i used to run an extension cord from the inverter, which i hid under the tongue, attached to the batteries.
now, i've hard wired the inverter to the batteries and ran the wires from the batteries inside to the cabinet that the tv sits on and hooks up to.
i plan on mounting the inverter to the side of the cabinet.
it was easy running the wires along the tongue, entering the front of the trailer thru a grommet for the other wires from the batteries.
i then ran them thru the storage area under the front bunk, around to the tv cabinet by the door.
