2002 Fleetwood Caribou 11j repairs

yes I saw the pics. A lot of work. Doesnt take much structually to become cost prohibitive having work done by someone. Been a few nose repairs by others, some looking worse than yours. 3 weeks is pretty good-3 years later even better!
Im unsure about the box. Looks like a task. Theres was a project couple of years ago doing a full lower box and wall repair but could not locate. There are a couple in the TCU thread-though more specificaly dealing with the slide support.
