The pace arrow was the top of the line fleetwood, they used all plywood in them.I have had quite a few different models over the years and most of them used particle board in there construction. The cost of a pace gasser was close to or more than the cost of some other brands low end Diesel pushers at the time, that is the reason they quit making them. They brought them back in diesel cost $228.000. I have a 1992 pace now, before this one I had a 1988 pace that the passenger side was all delamanated, I put a new side on it,that is a lot of work but it can be done. Take a close look at the 92 pace they are well built.
