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.

My thoughts also. The chassis builder installed tires that were well in excess of the axle capacity. Rather than buy a higher load rated tire the OP needs to buy a high load rated coach.
Not so true, the capacity for me and others was near max and with 20,000 lbs or more going down the highway at 65 mph in a big box that does very poorly in a crash only seems logical to up the ply rating to make these motorhomes as safe as possible, do you need me to load videos of motorhome crashes and list the death toll all due to tire blow outs.
Besides I am running over max so adding some extra safety is at least the best I can do.
Actually IMO, the best you could do is NOT run over max gross weight! IMO, most of the tire related crashes are because the vehicle is running with worn out/damaged tires, overspeed, under pressure, and/or over max GCWR, or any combination, not because of the tire sidewall plies. But hey, you're gonna do what you're gonna do!
