I just redid my 08 1191 at the beginning of the year, if you are doing it right it is no joke. I would say I had over 16 hours into it doing 1 side per day on the the weekends and the roof took over 4 hours since I was just cleaning the old caulk and putting new dicor overtop the old caulk. I totally stripped all the old caulk off the rest of the camper and cleaned it and applied new geocell proflex. All in all it took about 4 tubes of Dicor on the roof and 6 tubes of Geocell for the vertical surfaces.
I would say $1000.00 + materials is a very fair price if done correctly, but with the ways things are today that is probably $2000.00 if you can find someone that can fit it into their schedule.
