I can think of a couple of people. Hope I am not bumming said people out by beating the dead horse. My hope is SM devolps a max pack battery that will keep all the trailer folks in the beloved SM fold.
I fully expect Scout to get 350 miles on the BEV. That’s such a well-known number by now that they have to have a trim that gets at least 350 miles or they will disappoint everybody. I think this is likely more important than base price.
Can they get 400 miles? Absolutely. How much money do you want to spend?

They could “easily" decide to offer an upgraded battery, low-rolling-resistance All-season, 31” or 32” tires on 22” wheels, and a requirement to use “eco mode" to get 400 miles. The frame has plenty of space for a bigger battery, the GAWR of their axles will easily be able to handle a little extra weight (a few % more). The question is whether they can get the higher asking price if they offer it and whether they need to offer a lower towing capacity with that higher range. They would have to do a fair amount of engineering and testing to be sure they could consistently get that extra range. That’s not free.
The towing capacity of the Harvester is at least partially dependent on where they put the Harvester engine. If it’s over the rear axle or aft of the rear axle, then tongue weight becomes a limiting factor. If it’s between the rear axle and the front axle, GAWR matters more than tongue weight (but you increase noise, vibration, and harshness by moving the engine nearer the passengers).
I’ve done the math elsewhere in this forum. The basic idea is that for every 100 pounds of extra weight over or aft of the rear axle, you lose about 1000 pounds of towing capacity. To get the numbers exact, you would need to know the real weight and distance from the rear axle. Some of that can be mitigated, of course. All it would take is various upgrades to suspension, frame, axle GAWR, brakes, tires (LTs instead of softer tires) etc. I suspect the Harvester is already going to cost more than the BEV, and if it does some people are going to be unhappy—imagine even more cost related to the upgraded parts.
And if you’re upgrading parts, why not upgrade them on the BEV too so Scout only has to purchase one set of parts that are interchangeable between the BEV and the Harvester. But then you’re talking an HD/2500/3500 truck instead of a 1500 truck, you’ve harshed the ride beyond acceptability, and you’ve added $20k to the base price.
There’s also the concern about thermal management. With the massive amount of waste heat coming from the Harvester that needs to be managed, Scout’s thermal management system will probably have to be upgraded on the Harvester. If they separate the engine from the battery/motor thermal management, then it might allow DIYers to upgrade to higher tow capacities (see below).
I think the compromise is:
Harvester: max 7500 pounds
BEV: max 10,000 pounds.
Note that they will almost certainly use the same frame and axles for the BEV and Harvester. If that’s the case, and you know for a fact that the Harvester engine doesn’t push you beyond a safe GAWR, braking capacity, or thermal capacity it might be "simply" a matter of upgrading the suspension, switching to LT tires, beefing up the sway bars, increasing brake size, and a few other upgrades to push the Harvester to 10,000 pounds towing ability. But you’ll still have the lower towing capacity rating on the official VIN and door jamb sticker.
