I have a 2010 Bighorn 3670rl and am looking at replacing the leaf springs and axles. I have 7000# Lippert axles and just found out the 4 leaf double eye 25.25" springs from Lippert are 3000# rated. I have always under the assumption they were 3500#. I'm not over on my weight, last scales were at 15270# with 3180# pin weight. That puts me at around 12090# on my axles. I'm wondering if that is why i'm chewing the tires up on the insides on all four. I have taken the weight completely off the trailer and with a level their is the same amount of camber in the axles. According to Heartlands Manuals on the springs I would have thought with 16000# gross trailer there would have been 6 leaf 3500# springs. Or am I looking at it wrong.
