I'm not following why the F rated tire was near it's load max on your motorhome. It has a 3970 pound rating in a dual application, at 95 psi. That's 15880 pounds for your rear axle, still 1500 pounds over your loading and more than 2000 pounds over the axle rating of 13,500 pounds.
Sure the G rated tire is rated higher, 17,640 total, but it doesn't seem the F tire was overloaded.

14 ply/G rated tires have stiffer sidewalls so I will have less flex so the tires should run cooler with heavier loads, I am also over 14,000 lbs on my rear axle when I am towing my trailer, at 90-95 psi I have over 2000 lbs extra safe carrying on the G rated tires and less sidewall flex and that makes me feel a lot safer and to those on the road when I am loaded/towing 26,500 lbs at 65 mph..
To many blowouts from motorhomes already with deaths involved and its not always from under inflated or old tires, sometimes its from running near max weight and hot tires, I am trying to avoid blowouts..
Besides I am running over max so adding some extra safety is at least the best I can do..
