I want to tow 10,000lbs w/ SR battery.

[ICED Lightning]

it proves the old adage that once you get some 'weight' up to speed, momentum is your friend, but if that weight or object is NOT aerodynamic, regardless of the 'weight', it is going to be a BIG drag and will keep the momentum at bay, which is really what you NEED to tow efficiently, whether on your bike, or with your EV.

The only correct answer is that you can't legally do it. Tow more than the manufacturer's ratings at your own risk of voiding a warranty or, worse still, cause an accident and get sued. The engineers came up with those ratings for a reason.

The beauty of this New Ford LIGHTNING is that each trim level, no matter WHAT the price, is EXACTLY THE SAME TRUCK, from a build and capacity standpoint.
There is no difference in towing capacity from the Pro to the Platinum or anything in between, except for the size of the battery, and whether adding the Max Towing package for additional battery cooling, which then 'allows' for longer and heavier loads, at speed, but the TRUCK itself is NO different.
Ford has made this the EASIEST way to choose to buy a truck that can tow 5,000lbs right off the lot, or up to 10,000lbs, with the SAME EXACT truck.

Now, as for the legal aspect, I'll disagree. The 'road police' seem to come out on these forums from time to time, as though 'talking' to us as if we 'men' have never had any thoughts, concerns, or EXPERIENCE in life in driving a vehicle or towing a trailer. No, insurance does not, and cannot, decide to deny a claim simply because the owner decides to do what they do. No, the manufacturer is not going to give you the 'maximum' numbers, but engineers are going to give you the 'conservative' numbers, to protect the company, NOT to protect you. The 'police' don't really care whether your truck 'can' tow 10,000lbs, or 1,000lbs, they just want you to drive 'safely', unless you give them a reason to believe otherwise.

Regardless, the LIGHTNING, as for the truck itself, is perfectly capable of towing 10,000lbs, no matter 'which' version or battery or trim level you get. The BATTERY, though, is going to have issues, as far as the engineering supposes, if you try to tow 'too much' for 'too far' and at 'too fast' a speed. It's like saying a F250 with a 4cyl 100hp engine can't 'tow' a trailer of 10,000lbs. The truck itself can, yes. The engine power is going to be the problem.
These trucks are BUILT to do it. It's your choice as to whether you do it or not, or maybe decide with the Pro SR battery size and no max towing package to still tow a 10,000lb trailer on your farm for 100 yards from one point to another. It will have no problem.
If you want to do the same to go to Vegas with it, that's another story.

The more load you put on a motor the more current it will try to pull and the smaller battery just can not supply it

Exactly. The bigger battery has more modules in parallel to be able to supply (and accept) more current, not voltage. The SR and ER models have the same torque rating because they can accept the same amount of current for short periods of time but heavy loads for longer periods of time (horsepower) is what I believe the issue is here. Regenerative braking is also an integral part of the Lightning's braking system. Smaller batter, less ability to accept the charging current generated by heavy loads. It's not just Ford trying to screw you out of your money. The engineers came up with those numbers for a reason. It's your money. BLow it as you see fit
