They are only as good as the 'contracted' tow companies in the area.
They only call 'their' contracted tow companies. There might be a tow company with one mile of where you broke down but if it is not one of 'their' contractors you have to wait for one of theirs that might be 40 miles away.
I have to wonder why they don't have a larger data base of signed on contractors.?
AAA is know world wide and IMHO, JMHO any and all tow companies will take the road side service call because they KNOW they will be reimbursed same as will your own national brand car insurance tow policies. If you notice with them you are allowed to call the closet tow company and both will pay for it or reimburse you 100%.
Long story short IMHO GS needs to expand their contracted tow companies or change their history so all tow companies are assured they will be reimbursed for their service to an RV'er.
