With a cheap byte and crafting cost, the Trailer, paired with a Tractor, makes for good early-game rover trains
Up to 3 trailers can be connected together, though to use the trailer train a player would need a Rover Seat and a power item, such as Solar Panels or RTG, for the trailer to have the power to drive
Unlike the Medium Rover and Large Rover, the Trailer doesn't offer any power slots, making the need for power-generating modules a necessity for longer excursions
A single, disconnected trailer can still provide an infinite oxygen source for a player
