I am not sure what is the advantage of Ecohitch from Torklift over the one from Curt? Curt is 37lb vs 36lb from Torklift Other than the ease of installation, there isn’t any other I can find. The weight of both is the same, and the price of Curt “installed at Uhaul” is $70 less than that of Ecohitch. Am I missing something here ?!
