I have a few questions about a doublewide I inherited from my grandparents. It is in very good condition and I am renting it right now. My question is I have the title but it doesnt mention a serial number or manufacturer, this is a 1971 model. My insurance company requires these things before they will insure it. I have read as of 1976 to present where the ID and tags are but what about a 1971 model. It is on block foundation so that might make it hard if the ID is located on the frame, is there other places in the mobile home it might be located. It has the original circuit breaker box, but not the water heater or furnace. Any help would be appreciated. This house has been well taken care of over the years and I hope to keep it for several years to come as a rental.
