Carlisle HD owners feedback please!

I've had them for over a year now. About 5,000 miles on them without issues and most of those miles are along the coast in the heat of summer. I really like the 81 mph speed rating, not that I'm going that fast but I do usually run right at 70 mph so it's a comfort having that cushion. I overkilled also and put Load Range E on out camper. I know looks of a tire aren't everything either, but they really look like a heavy truck tire whereas typical trailer tires always look flimsy.
