The frame is pretty easy, what you have to do is make sure you have the tail gate on, and open, make sure you cut the frame back far enough to clear the tail gate, otherwise it will not open. You will have to cut the rear hangers off. then add a second piece of square tubing under the frame to extend the frame. this is where you will add your rear spring hangers. This will also add a couple of inches lift on the rear, which always helps with the 4runner. At least this is what I did, and it seems to work just fine.
As for the windows on the camper, just got some plexiglass, cut it to size, and heat it up with a heat gun at the right spot and put a bit of pressure to cause it to bend. Worked just perfectly. You can check out my build to see it all work out.
