Roadside assistance and "tow to the nearest authorized facility"

Looking for a plan for a new motorhome. It appears that Coachnet doesn't have a  limit on mileage which will be handy out west. My concerns are we are getting a F600 chassis. Service centers are few and far between. Coachnet says tow to the nearest authorized facility. What if they are a month behind? Does Coachnet make allowances for that? if not what can you do? pay the difference between where they want to tow you and where you want to go? Or do you leave the motorhome, rent a car and drive home (if you don't have a toad). What if you are towing a cargo trailer with a sxs in it? I assume they will tow it too but if you have a several week wait what do you do with it?

Thanks
