We just bought a 2014 Bighorn 3585 and I've been going over everything to get familiar. One thing I noticed is that the spring shackles don't have lube points. Our previous 5'er had the wet bolt system from the factory. Does Heartland shackles not need lubrication or are they "wet" by other means??? We're looking forward to our Snowbird trip to Florida next month and would like everything tip-top. Thanks.
