Not sure about the LM, but for the most part, when a tow hitch is put on after the fact, and not done with production at time of factory build, the true weight will be unknown. Just because they say it can pull a certain amount of weight does not mean by putting the hitch on afterwards the trucks capabilities are the same. If it is not a factory item, which in this case it is not. I would be extra careful pulling anything heavy with your LM. You dont want to ruin the transmission, nor cause any other damage that would cost significantly more to fix, especially on such a rare vehichle. In my opinion, i would refrain from pulling anything more than 1500 pounds.
