Sealed Roads

[Twotribes]

Ok I understand that with dirt roads you wanna put a truck stop every 5 or so hexes and with sealed roads it is every 7 or so. Do sealed roads also increase logistics flow so you can supply a bigger force at the end of the line?

Bro, that's way too many truck stops. A lvl 1 truck station with dirt roads gives full logistics points for 10 hexes. Even without supply dumps and sealed roads, you would only need 1 truck stop every 19 hexes. Although that number drops a bit when you start adding branches.

You could build extra truck stops just to juice up the capacity, but it's more efficient to upgrade the truck stops than to build a bunch of lvl 1's.

Indeed--what lloydster4 wrote.

Not an answer but consider the implications of Where do I put a Supply Base?.

Truck stations should be separated 15-20 hexes. 20-25 hexes is fine with late-game technology and industry.

To add to what the others have said, sealed roads don't (directly) increase capacity. What they do is extend the range at which your truck stops can operate. So if hypothetically you had a a truck stop that provided full logistics for ten hexes but started to drop off after the eleventh, replacing dirt roads with sealed roads would allow the same truck stop to provide full logistical capacity for, say, nineteen. If your army was hanging around along the ten hexes they won't notice any difference from the sealed roads, but if they were hanging around the seventeenth hex they'd go from almost starving to good as new once the sealed roads go into play.

As the others said, that is way to close.

You get 100 Truck AP. Dirt Roads cost 10 Truck AP per hex. The city hex does count, so you only get about 9 Hexes of full capacity distance. On a sealed road with 7 AP, it is 13 Hexes. of course, excessive branching does muddy the waters a bit.
Trucks from that stop can drive that far, before they start loosing Capacity to distance. They still got some trailing capacity for the rest of the road, but never try to rely on that.

Truck AP do not relevantly increase with Upgrades (+5 per level. On the 100 base, that is almost nothing). So one planning fits them all, more or less.
