I have researched ways to level my fifth. It's limited. I have a pull rite slider with no vertical height adjustment except to purchase lower profile base feet. I gain 1"which I will do.
Next option is to raise my pin box. Again I can only raise it one bolt hole. A gain of another inch.
Is this a difficult task? Looks like eight bolts to loosen and tighten. It looks like the average pin box weights about 100 lbs. Also hard to find manufacturer info for torque values for tightening.
Attempting this myself to save some $$$
Looking for suggestions.
