NHTSA Complaint #11670763 — 2021 GRAND DESIGN SOLITUDE

On the evening of 7-1-25 we had finished unhooking the rv. As we were setting out our leveling blocks we noticed smoke pouring from the front battery compartment. After we had disconnected our batteries via the battery disconnect switch and removed the batteries we were able to search out the cause of the smoke . The power cable from the tow vehicle where it makes connection to the camper was inserted into a metal box. The connector to the box had come free allowing the cord to rub through and short to ground on the metal box causing the wire to burn back through the wire bundle into the battery compartment. This melted all the wires in the bundle and fused them together . There appears to be no fusebile links in line to protect against thermal overload. If we had not been parked and unhooked we would not have been able to respond so quickly to disable the battery power .
