For the most part you are losing by being a solo and doing both. Different tools and maybe even a different trailer. Always some toll sitting idle not making money. Losing money (time) when you transfer from one set up to another. More maintenance of stuff and more cost in equipment and storage. A large company with crews doing different things - sure, but I believe the solo hurts himself. Why spend another 4K to set up another thing when you can just keep cutting??
