I have it, but have never had to use it. I do have friends who have needed it and say they are fabulous. Very responsive. However, be aware that some major highways insist you use their contracted services (such as the NY state thruway) In cases like this, US rider contacts them and uses them for you, so it may not be who US rider prefers. I actually asked them this since I trailer in NY a lot.
I keep US Rider for several years already. Knock on wood never used it with the trailer, but I called them when I couldn't start my car and the first thing they asked if I haul a horse and if I need a help with it. Almost every horse person around here has US Rider, and some used it and were very happy with service.
P.S> I used AAA twice and both time it was a horrid experience...
I will be getting it soon. Had first breakdown hauling horses today. Thankfully, we were only around 50 miles from home and friends came and picked up the horse trailer. AAA took care of the truck, but if we were not as close to home it would have been a bigger problem.
I am not sure if they are roadside assistance to replace AAA (for the vehicle alone) or not. That is a question I have not asked. But if you are towing your trailer, empty, or filled with, for example-buffalo (since a friend of mine needed it then....)it works.
The only thing I saw on their site that concerns me is that we would have to pay double of what we are paying for AAA if we want both me and my husband covered where AAA covers us both. Will have to think on this a bit.
