Capacity is a ceiling
The optimiser checks that the freight fits within the vehicle's limits. It does not decide, or need to decide, whereabouts on the deck each item ends up, which is the only thing that determines the axle split.
Head to head
PTV comes at freight from logistics optimisation rather than from maps, and the tour planning is a serious piece of work. It stops at the trailer door.
Who it is for
If your question is which of eight vehicles takes which of forty drops and in what order, this is the category leader's category.
Tour optimisation is a much harder problem than it looks. It balances customer time windows, driver hours, vehicle capacity, cost and tolls. It also uses a road network that treats a truck differently from a van. PTV does all of that across a fleet before the day starts, and its experience shows.
On top of that sits truck attribute routing, toll calculation, transport cost calculation and arrival time forecasting, with road coverage across Europe that reflects decades of work. For a continental operation, that local depth is not a detail.
The result is a plan that says this vehicle, these stops, this order, this arrival time, this cost. Every one of those is a decision worth money, and none of them is a decision about where the pallets go.
The optimiser decides what goes on the truck. Nothing in it decides where on the deck any of it lands.
Two layers, not two products
The job it was not built for
An optimiser knows a trailer can take this much weight and this much volume. That is a constraint, not a layout.
The optimiser checks that the freight fits within the vehicle's limits. It does not decide, or need to decide, whereabouts on the deck each item ends up, which is the only thing that determines the axle split.
Drop order is chosen for distance and time windows. It also decides what remains on the trailer after each stop, and therefore what each axle group carries on every leg after the first.
An optimiser minimises a cost. Statutory axle limits are not a cost to be traded off, they are a hard boundary with a citation on the other side of it.
A worked example. Nothing was added at any stop. The heaviest pallets were nearest the doors, so the first drop moved the balance forward and put the drive tandem 700 lb over between two deliveries that were both on time.
A sequence chosen for distance and time windows also decides what stays on the trailer after every stop. Reverse those four drops and the same freight on the same road never crosses the line.
Side by side
Optimisation, tolls, transport cost, navigation and European coverage all belong to the other column.

Methodology
When to pick them instead
Your hard problem is sequencing. Many vehicles, many stops, time windows and a cost function to minimise — that is PTV's home ground and it is a serious piece of engineering.
You need transport cost and toll cost calculated as part of planning, not after it.
Your operation is European, or crosses Europe. Depth of coverage and local rule knowledge there is a real differentiator.
You need arrival time forecasting your customers will be held to.
Working together
Sequencing forty drops across eight vehicles is a genuinely hard problem and it belongs where it already is. Nothing here competes with that.
Once the optimiser has decided this trailer carries these stops, the physical question begins: where does that freight have to sit for every axle group to come back legal.
A tour with four stops is four different loads. The axle verdict is recomputed for each leg, so a sequence that is legal at the first drop and illegal at the third is caught before it is dispatched.
Legal, over, or permit required, on every leg of the tour, with the binding rule named rather than a bare refusal.
