I have a proposal, but I’ll say right away that it’s not exactly about cargo transportation.
This mod is currently very well suited for expansion on a large map. If you need to land on an island 10 km from the main base, you’ve given us a lot of tools for setting up an outpost. There’s everything — a mobile radar, transportation independent of railway tracks, drones, and much more. Essentially, there’s just one unresolved issue: there’s no connection to the main base’s logical network. So we could build some kind of small transmitter (similar to a radio). which could transmit a logical signal like a vanilla radar, but at the same time consume little energy and not scan the surrounding world, and be compact (1 tile, for example) Such a transmitter would complement all mobile devices and make the outpost fully self‑sufficient by transmitting a logical signal via radio.

Thanks, that's a great idea! If I understood right, you'd like a small, cheap radio transmitter that shares circuit network signals like the vanilla radar does, but without scanning the map. I'll think about how to fit it in. Maybe even the radar truck could do it when deployed.

Update: I went with the radar truck! In Heavy Trucks 1.3.4, the deployed Radar Truck shares circuit signals with the other radars, just like the vanilla radar. Plug a red or green wire into the middle of the deployed truck, and your outpost's signals reach your base, and the other way round. When you fold it the wires drop, and when you deploy it again they plug back in, if they're still within reach. Let me know how it works for you!

wow! thanks!
