I have road service with my auto insurance. I have my MH and 2 cars insured under one policy. A feature of that policy is road service $4 a year.
I used it once for an RV in over 43 years. About 10 years ago I got my old 35' MH stuck in sugar sand along side a highway outside of Wilmington, NC. I called the NC state police and asked them who they use for large vehicle towing. I called that towing company and had a Peterbuilt wrecker in half an hour. He winched me out backward by hooking on to my MH trailer hitch. I paid the tow truck drive $100 cash and got a receipt. I called my insurance company and they told me to mail them the receipt. In less than a week I had a check for $100 from my insurance company.
I have never had any other type of emergency road service.
