Well, under your described conditions, the motorhome tires probably could be run for many more miles.
Rear axle and semi-trailer installations of recapped tires is just a balance between cost and risk. (Many recaps will run as long and are as durable as the original tread.)
A blowout on a non-steer axle is an inconvenience and downtime for a revenue producing truck, but that risk is mitigated by the number of tires in use and cummulative reduced cost of using recaps for the fleet.
A blowout on a non-steer axle of a motorhome may entail fiberglass and other component damages that just do not exist on a trailer or truck.
Also, the inconvenience of that blowout happening in some remote area of travel without a support group to get it replaced makes the risk of substandard tires (recap or original) less than exciting for most motorhome operators.
A blowout on the steer axle of either vehicle is equally dangerous and to be avoided at higher cost.
JMHO and experience.
