Especially when i'm working on Live Production on location, i'm always thinking about where my ATEM setup would be. Sometimes you have to bring your own table, but here's an alternative option - a full 3 shelf Folding Portable Rack.
These racks are light enough to carry and fold down quickly to transport in your car. They setup just as fast without tools and is a good way of keeping your bags together and off the floor. The wheels make it easy to move gear about, and there's been times where i've even gone as far as using cable bike locks with my hardcases to ensure they don't wander off. I'm showing my Medium sized version, but the smaller version (only a few inches shorter) starts at around $40 dollars. They come in a variety of sizes, but for travel and to maintain a low center of gravity it's better to stick with the small to medium models with casters.
Don't break your back or wear yourself out moving gear! The AMG 750 Cart is a multi-use gear cart that can convert into 3 different modes and hold up to 750lbs. It folds down compact enough to fit in a small trunk.
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.
