Hi I have a 2001 dodge 2500 and a 2007 texas pride dump trailer, I would like to install a trickle charger but cannot find good directions to do it myself anywhere on the WWW is there another name for a trickle charger I should know to search for? I have the standard 7 way RV plug I understand the center is hot - what size wire do I use - do I need a in-line fuse - does my Dodge need a fuse added like a newer chevy to function properly - do you connect just to the + of the battery? I appreciate any light you can shed to this problem. I do understand some people idea to run straight off battery or under hood I am light user and think the trickle charge would satisfy my dumping needs. Side question: Does anyone use these solar units successfully the way our stuff gets beat up I can't imagine a solar panel lasting too long anyways. It is damn sunny in Colorado though! Thanks everyone!
