Tow Vehicle Battery and Alternator

There is a blog called the "Adventurous Way". A young man named Matt Knight and his wife(Mrs. White?)are boon docking there way thu all the state parks. He has posted several "charging" upgrades he did on his rig. The last one I read was specific to this subject. He detailed it from start to finish. He got real successful results. Successful enough to cause me to consider.....but I have several other irons in the fire right now! And just for the record, I know nothing about blogs, I just stumbled upon it as someone posted a link to this episode of the blog on an Outdoor-RV forum or Outdoor-RV Facebook page.
