Evidentially I am told that the newer V10 fords have very similar torque range ( a model change with an extra valve)
Ford's tow ratings are on the internet. The gasser puts out about half the torque of the diesel. This is significant as it is torque that gets you up the hills. Also, the Ford tow rating guide provides deducts for altiitude for the gasser at about 2 percent per 1000 feet, the diesel being turbocharged does not suffer a deduct. In places like Denver the loss for the gasser is 10 percent of the tow rating. And the tow rating also provides for frontal area. You might acquaint yourself with the towing guides and understand the differences between axle ratings and engines. Also, most of motorhomes that are gas are less than 26,000 pounds. Most heavier are diesels. It might make up your mind as you look at motorhomes and their size and weights.
This is the myth that just refuses to die. It is NOT, repeat NOT torque that "gets you up the hills". It is HORSEPOWER. 350HP is 350HP, be it from a Detroit Series 60 at 1400RPM, a Cat C10 at 1800, a Cummins ISB at 2800, a Ford V10 at 4500, a turbocharged Honda at 8000, or a turbine at 45,000RPM!
