8R19.5 is still a volume tire size. It is a UPS, Fedex size. It is a "truck tire size" but, I would expect to find it by all three major manufacturers. I think you will find that Goodyear's model designation is G670 for a steel/steel.
I don't know what you are looking for in terms of ride & comfort vs. mileage and durability. The first decision is whether to buy a fabric/steel or a steel/steel. This means polyester fabric carcass/steel belts or steel wire carcass/steel belts.
Maybe some of the folks who have the motor homes will give you an opinion on fabric vs. wire carcass. Look at your current tires for the const. detail on the sidewall.
Then start looking for dealers that handle truck tires. RV dealers, Camping world, major tire dealers.
