I’ve been using Equalizer exclusively. First the 10k model on my previous trailer. Now the 16k model on my larger trailer. Both have been fine. A bit of a fuss to get them set up properly, but you only do that once. They are also pretty noisy on a sharp turn.
Make sure you buy the size based on maximum tongue weight. This will always govern since they always spec based on 10% of the max gvw. In other words, a 10k trailer will need at least a 12k hitch, as the max tongue weight on the 10k hitch is 1000lbs. I have the 16k for my 11,295lb gvw trailer because my tongue weight runs 1500-1600 on that particular trailer model. It is known for being “tongue heavy”.
