Because I rarely venture too far outside my own area code any AAA towing I need done would be directed to one particular large, reliable and frequent provider for them here locally. In fact they typically bill AAA TWO MILLION dollars a year.
They're that good!
As I've had this outfit two twice for me so far I have a bit of a slight working relationship, have their direct contact phone numbers I can call and get them ready to take the call from AAA. I don't know this would work for everyone but relating to the longer distances they'd be willing to accept AAA's limits of payment and just charge me the additional mileage cost if any would apply.
As I'm almost never more than 130 miles from "home" if the first 100 miles are covered I'm not facing astronomical towing charges. Because this bunch is reliable and I like their approach to business I'm okay to pay them---they're known to me and well worth what they charge.
If you're in a similar situation as me try working with a AAA affiliate tow operator---it might be well worth the effort.
Most likely though the RV+ Premier policy would work best for the SMB-type vehicles---you'd be covered almost regardless what you're driving at time of need.
