I bought a new hitch receiver for my 2019 Niro. It is a class II, bolt on, custom fit, 3500 # GTW and 350# tongue weight with a 1 14" receiver . Curt Mfg. co, Part number 12171. Fits 2017, 2018, 2019. I intended to pull a 4500 # utility trailer with tongue weight of only 100# but am having second thoughts because it exceeds the GTW limits. What are your thoughts? Use it or sell it?
