1995 Ford Ranger lighting problems

I was driving down the road when I smelled smoke and saw flames coming out from under the hood and the power to the vehicle began to cut out making it difficult to move or steer the truck to safety I then exited the vehicle and flames were coming out of the front passenger side good and headlight. So I called the fire department and they came and sprayed the truck putting the flames out. And cutting the wires to the battery

I was pulling a small trailer going about 15MPH out of my driveway and felt the trailer drop off of the vehicle I stopped and got out and noticed that the last 2 feet of the rear frame rails fell out taking the license plate lights and bumper with it. After I realized that the rear frame rusted out, I inspected the whole vehicle and found that the radius arm bracket has holes in it, I had to replace all of the shackles, the driver side cab mount rusted out and now has fallen out of the vehicle, I also have noticed…
