I think what is most important when buying Towing insurance for an RV, is that the company you are hiring is aware of what's involved with towing a 30-45 ft RV.
Not all towing company's are set up to Tow 30 to 45 ft RV's
This is the problem with assuming the towing option on your insurance policy includes the RV coverage.
If you go with Good Sam or Coach Net the most popular two , they understand what's involved.
If you go with Allstate,Geico.Nationwide,etc they may or may not be able to handle the size of your RV.
When you are stranded on the side of the road is not the time to do your research and start reading your policy. Do your research up front.
We have had Good Sam ERS since the beginning of our RV travels and they have always done a great job. I thought about changing to Coach Net a couple of times because I liked the technical support hot line. Then GS ERS offered the platium option which also offers the Tech support, so we stayed. We pay 129.00 a year and it covers the RV, all of our cars and our Harley. Until they let me down I probably will not change.
You need the machine to do the job.
