Oh , and just for arguments sake. Tbh i dont think the zerk fittings are the cats meow, as i said you still need to check the stuff every 5 years or so depending on use. I repacked my stuff 2 years ago, and while I dont do a lot of trips , I usally do 7 or 8 a year, with one ling one from NJ to fl. But most trips are between 3 and 6 hours one way average. My grease was totaly fine. I did not use the ez lube fittings yet, except to test them. I do plan on using them for yearly maintenance. Then inspect every 5 years. So, no need to repack everything every year. At least in my case. The quick connects will do the job or maintaining for every year greasing. If they dont ill let ya know.
