Debating on buying a model X, however, we have a roughly 3500 pound Alumacraft 16' fishing boat with trailer. It would need to be able to tow it between 50-60 mph and get us about 120 miles on a full charge. Is that impossible to do with the 75D? I have seen reports all over the place of anywhere between 500whpm and 1000whpm but that seems to be mostly people pulling campers that I'd imagine are much less aerodynamic than the fishing boat would be? From what I understand the killer is speed and drag, not weight. So I'm hoping those who have a boat similar to mine might be able to chime in with their towing results at those speeds?
