I can tell this going to be a long forum.......................Yeah a smaller pulley will help..................IF you are going to put out some decent volts with the alternator. If you are using more than you are generating then you will lose from the Get-Go. The smaller pulley will assist in getting the alternator turning faster sooner, and if you are not dragging the system into dry shutdown it will keep up. I am just telling you that maybe you should Upgrade the alternator to make sure that you are giving it what you need. Try the pulley first, but look at what else you could do to get the system working better also, because I am thinking that you will have to in the end. Now for a scarey point that to this story. If you choose to put the batteries under the bed you will get them away from the heat in the engine compartment (good thing). Battery capability decreases as they get warmer, cooler is good. However, you will need some serious battery cable to keep the loses from resistance down. Mnay guys that do something like this go to the local welding supply shop and get heavy welding cable to use for battery cables. The bigger the wire and the more strands the better. Current travels along the outside of a copper wire, thus more voltage available at the load (stereo, starter, fans, etc,)
