I don't know the gear ratio, but the Seneca Freightliner is a truck and acts like a truck. Many times our accelerator is to the floor, when leaving a stop light or climbing a hill. That is with towing a 4000 lb. vehicle or not. Automatic dump trucks and road trucks act the same. A big standard transmission with a transfer case may give you the feeling of more power, but you are not going to accelerate any faster. Its just how they work. The Seneca Freightliner can "legally" tow up to 10,000 lbs. Some other units can tow up to 40,000 lbs. They will accelerate about the same. And thank GOD, they all have good brakes.
