Hoping someone can help here, and tell me what I am doing wrong. I have a 2000 Coleman Sedona I bought laspart t month, and I am trying to remove the AC Shroud. There is quite a bit junk inside of it (pine needles, dirt, mud dabber nests), and it could use a good cleaning removed the 4 screws on top, and the two side screws. I can lift the back up quite a bit, but the front feels stuck, I can move it a little but it won't come up more than 1/4 of an inch. Should it come a part in two pieces or one?
