Here's another product we checked out over at PhotoPlus Expo 2013 NY. INOVATIV CARTS offer three main lines of equipment carts, each with three different versions depending on your needs. Accessories can be added to each cart to further customize the product according to your requirements. The carts can be broken down and folded up for travel without the use of any tools.
If you're shooting as a hobby, these are definitely pricey with the smallest Scout version starting at around $2500 dollars. If you're a professional who's shopped around, this is one of the more affordable portable Equipment Cart systems. I'm a big fan of rolling carts, and use them every single day, but I'm only using very cheap tool carts in the studio (as seen here). My cheap carts definitely aren't made for travel.
