The first couple of trucks we built we made our own carts, because we were not happy with what was currently available on the market. We found out it is a very time consuming, exacting process. After seeing Studio Carts on set and meeting with them we decided that they would be a great fit for us. Studio Carts has way better design than some of the other carts in the industry and are made very well! We have decided on the next truck that we built, we will just have Studio Carts build the carts for it, since they do a great job and can do it quicker than we can!
