choosing insurance is always big headache and homework.
When there are specific RV insurance, most of the time they offer "their choice" of appropriate shop to tow you to.
That not always is a good thing.
Lot of truck insurance will offer towing for as low as 10 bucks a year, but learn about their limitation.
One of the reason I bought new truck for cross-country retirement was the warranty and roadside assistance included.
I recall 1 of our youtube spammers having the unpleasant experience and posting video about it.
