Generator..... if you mount it on the tongue (bolt it down good to prevent theft) be sure and make a cover for it to keep it from weather damage. Lights......use floresant for the inside of the trailer, but use T-5 light fixtures. Two, 2 bulb, four footers inside should be plenty. One 2 bulb, with 18" small chain with hooks, will be good to put up in your easy up tent. put outlets in your trailer and carry a few extension cords and you should be good to go. old type flouresant will work, but they require a lot more amps and without a heavy generator the ballasts won't last long. You mentioned a war wagon, but there are several different types. We have two different ones, but I may part with the custom built one that is actually a kart stand with onboard air tank and underneath storage. Aluminum treadplate top with white sheet metal covering. Custom built, pretty trick and pretty cool. If you are interested, pm me.
