The Conastoga Wagon

The Conestoga wagon was bigger. The top of a Conestoga wagon was 28 feet long. The ends were raked -- they slanted outward from the bottom. The covering then provided more protection from rain and the cargo space was slightly larger. The floor of the wagon was curved so that the load wouldn't shift. The Conestoga wagon could carry 5000 pounds.
Conestoga wagons were large, sturdy wagons usually pulled by six horses. Their strong, broad wheels made them capable of crossing rutted roads, muddy flats, and the non-roads of the prairie.
The Conestoga was used to carry any type of cargo. Before the Revolutionary War, some 10,000 of these wagons made the trip from the Dutch Country to Philadelphia...
