Bug Out! Part 4: Mortars and Motorhomes

In Bug Out! Part 3, Frank and Jane survive the onslaught of enemies from inside and outside our borders. Now the enemies have teamed up!

The enemy has targeted our group, at first for their supplies and vehicles, but now it's worse.

The fortifications they've built at the RV Park have been good enough to hold off small attacks, but will the attacks continue to be small? Motorhomes aren't a hard target.
