We are interested in a 2007 Keystone Zeppelin II Z242 with significant delamination of the front end cap and moderate delamination of the rear end cap. If we seal it up and keep it sealed will it continue to get worse anyway, or is it something we can likely live with? J D Power lists average retail for this model and feature list at $9235.00 and low retail at $7650.00. If the delamination is something good maintenance going forward will allow us to live with, how much should it affect the price? Is delamination likely figured into J D Power's prices for something this old?
