The ATT (armored trailer tow) series is many techs that I have made to be linked together into a very long "train". I have made many options for you use with your ATT, such as a helipad to land and recharge helicopters on it or a heavily armored gun trailer to obliterate any enemies that approach. You can also just hook up a bunch of flatbed trailers and put all your resources on them, or make a house on one and tow it to a spot of interest. The ATT can carry a VERY large amount of weight, and can even climb over mountains using the thrust it has. It can also carry the needed battery power for all connected techs (battery power is transfered down the line via a series of wireless chargers)

Many additions to this series will come, so be prepared!
