Personal loans: "Free up cash" vs low interest

[Champ Leong]

I have a very good interest rates on my truck and home. 1.99/2.5. I have considered paying those down to "free up" cash long term, but I'm also considering the facts that my loans, especially on the truck, are  nearly FREE MONEY. The 1.99 is 7 years while the 2.5 is 30. I don't save very much on the 7 but I save a lot on the 30. What are the advantages/disadvantages of paying off these loans early? TIA!
