It's pretty easy. I cut a little out of my inner frame to insert a new crossmember. Once the new crossmember is in you can cut out the old spare tire crossmember. Then a couple pieces of angle iron welded to the new crossmember at the right angle, extend the wires and lines, and cut the bed. I always set them up with the front tires a couple inches off the ground and the rear end down and a 2x4 under the tank. This just ensures you'll never drag it. It's also not a bad idea to add some braces to the angle at the end by the axle. Here's a pic.
