Do you need a trailer that you can just pull up to the job site and get right to work without having to unload all your tools. The problem with most trailers is the limited access to your tools. If you need something in the back, you have to unload everything in front of it.
I have always looked at the Festool MFT (Multi-Function Table) as great little work table, but not practical for jobsite use. I just never liked the idea of having to carry it around on the jobsite along with all of my other tools. But Timothy Wilmots' modified MFTC (Multi-Function Tool Cart) looks like an ideal way to transport both the MFT and your tools.
We have seen circular saws used as table saw replacements with the Eurekazone tracksaw system, and now there is a new system from PUPS (Portable Universal Power Station) that can turn a circular saw to an accurate miter saw.
We have seen a couple of combination miter/table saws now enjoying freedom in the U.K., one from Bosch with a table mounted on top of a miter saw, and one from Makita that flips to transform. Now it is DeWalt's turn to join in on the fun with their very own flipping combination transformation miter/table saw.
