This is the quintessential wagon prop that every fantasy GM should own. It makes cavaran encounters much more fun when players can see and manipulate the wagons themselves - you'll find your players jumping on top of them, hijacking them and driving them around, or using them as defensive barricades. I highly recommend pairing it with Dave's Cargo Bales (http://www.rpgnow.com/product/93496/Cargo-Bales-Paper-Model s?manufacturers_id=2985) so you can fill up the caravan with goods.
Best wagon set ever. Not only can it be for the old west as in the model shown but it also provides models for Pirate adventures and wagons all the way back to the Crusades and even The Roman Times of Julius Ceasar. Also, These wagons are not just show pieces bt they provide space for player Characters to ride within.
The next time that you plan a traveling encounter in your game, any of these wagons will provide a fantastic improvement to that encounter. The wagon and horses may decide to continue on without the pc's while the encounter drags on putting added tension and a time limit to the pc's decision making.
