Well, I agree you have to be careful with hitch weight, but that can be adjusted to a certain extent with a good WD system. The equalizer 4 points did the job, but we had to crank it hard. Note that mercedes likes about 8-10% on the hitch, NOT 15% used by domestic trucks. I disagree this relegates you to ultra lights though, as long as your base hitch weight isn't too high to start with. The Nash 25c admittedly was right at the limit. We had to load it heavily towards the rear otherwise it was notably harder to drive,
