Usually this kind of thing turns into lots of work with beer and shovels or someone rents a tracked skid steer (depending on the financial inclination of those involved).
In this case tow company added a 3rd wrecker to the mix since they had to get their own trucks out.
They got an even bigger wrecker (with a third axle, helping to spread the weight). The end of the article said it freed the home, Big Blue, one yellow wrecker, and was then working on the last.
I can confirm. I was there a couple of times over the last month and none of this mess is remaining. It was all white and flat with a fire burn marks from tires and fire pits.
What was the outcome? Were all the vehicles able to be pulled out?
