Truthfully, I had a few estimates over the years for paint work on rv's and they have been outrageous. What really hurts is the labor involved and also supplies. The estimate I got to repaint the front end of my class a (southwind) was around 5k. I ended up doing it myself, base coat, clear coat for about 450.00. Same with my pace arrow, I did the whole lower half baggage areas for about the same cost. But if your not a painter, you have to absorb what it is. 2K for a front cap sounds reasonable too me. I'd pay that price to have it done instead of tackling it myself.
