With the gas engine I would keep the 5th wheel trailer with its rated load to less than 9,000 lbs. of weight. And as was already mentioned I would want 4.10 or lower gears and have them changed on the truck if you have 3.73 or 3.55.
With a gas engine the same truck with 4.10 gears has a 25% greater tow rating than the truck with 3.73 gears, and 3.73 equipped trucks are rated 25% higher than one with 3.55 gears.
What should be considered in terms of comfort and safety is how much distance your vehicle with its trailer will need to get up to 55 MPH and be able to merge with traffic on the highway. This is where the lower gears make a very big difference.
For towing the lower gears will often result in better fuel economy as the engine is pulling the load while at its optimum RPM range.
