I need advice on my totalled yet still beautiful baby.

Bad deal, I'd be wondering a lot with what went wrong. Sorry to hear you lost your baby.

I've restored a badly damaged trailer and the amount of labor required is quite large. I don't think it's in your best interests to try and recover it but the insurance company will let you buy it in lieu of the salvage amount they would receive.

At the end of the day, you could buy a new "baby" something lightly used and camp with your boys and Mom. I found it's not so much about the amenities but the experience that makes camping worthwhile. Another alternative is renting a cabin or RV, sometimes it's an easier situation.
Hope it all works out for you and that your health stays up, good luck.
