Trailer Power - Xantrex 600HD

A few days ago I ordered the Xantrex Powerpack Xpower 600HD. This will serve as my rechargeble power plant in our trailer to run 120V appliances or tools and to run lights inside the main compartment so we can see our gear at night. I plan to run a 12V power line along with the trailer lighting wires from the jeep to constantly charge the battery when the jeep is running. This will be a less costly (only $93) and simpler system than using car batteries such as Optima's and wiring a charging and distribution system I think. UPDATE: I don't plan to do any extended trips anytime soon, just weekend get-aways in Colorado. So, rather than wiring a 12V power supply through my jeep, I am installed a solar trickle charger. You can get a cheap panel at Harbor Freight and then buy a blocking diode on ebay which prevents the panel from working in reverse during the night and draining your battery.
