I didn't know until now about the US Rider help assistance. I do almost no trailering with horses anymore, but there was one time I sure could have used the coverage and gladly paid the monthly premium(sp?).
I was taking my Granddaughter, my mare and our POA mare to a week-end horse camping and Benefit trail ride about a 2 hour drive to get to the campsite. All of a sudden going 60 mph I had a shimming and shaking going on with my truck and trailer. I pulled over, got out of the truck and walked all around the trailer and truck. I didn't see anything wrong or amiss so I got back in the truck and started off again. Got about a mile further and KA-BOOM, a dust cloud covered us, by Granddaughter went ballistic and I had a situation!!!
I got out and a rear tire on my truck had blown to pieces. I thank my lucky stars it wasn't a front/steer tire that blew. Fortunately 2 men and their wives saw the tire blow and stopped to help me get the spare on the ground. Instead of going on to the Benefit I took us back home and the next day my DH took the truck and got 4 new 10-ply tires put on the truck.
