For about the last 5 years or more, I have purchased for myself the ERS through the Explorer RV Club. I also purchase the ERS for my grown children for their Christmas present. It is a great gift for them and something that, it appears, they always use—calling for a flat tire, battery boost, or running out of gas. Every time that we had to use it ourselves, or they had to call, we all received excellent service. I would highly recommend it to anyone to purchase the ERS through the Explorer RV Club.
