Tabletop Props has a Kickstarter campaign going to try and fund a new covered wagon terrain piece.
From the campaign:
I chose the Covered Wagon to be the flagship piece because of its versatility. Whether you are into fantasy tabletop games, war games, or toy trains, this Covered Wagon is perfect for your hobby.
There are a total of 16 pieces that make up the complete Covered Wagon, each of which is removable.
The base alone is fully detailed and allows the Covered Wagon to become a simple Wagon Bed. What will you do with yours?
