Would entirely depend on what your legal for on the trailer there, how heavy the hitch on truck is rated for, as well as trailer. Going to guess trailer weights about 4 tons, if you're say legal for 17 tons on trailer axles you could easily put 4 ton on the pin leaving you room for 17 tons of load on the trailer which would give you a 160 in most cases. If the hitch on truck was up to it, could easily upgrade to a tridem and put a 200 on it. I put my 210 on a 25 ton tag and pulls great. I actually found the truck pulls it better with more pin weight. I started with 10% so 3 ton on the hitch, but put machine further forward to put about 5 ton on the truck, and truck pulls it easier and has a lot more traction on slippery roads.
