Here in the Tampa Florida Market Low Retail from a Dealer for the 1995 Brave on either gas or Diesel chassis is $8,550 so around $5,000 private sale however with noticeable de-lamination you could be looking at $3,500 or less.
You can start here, select the model you have and enter your zipcode to get the NADA book values and lower the price to about 2/3 whats listed there for a private sale and then adjust for the delam issues.
Your market could show the same, lower or potentially higher. Asking is not getting and most when they see issues will naturally go for lower so your asking needs to be moderately higher without scaring away buyers so their lower will not be too absurd.
One should note that Winnebago had major problems where the de-lamination would be toward the middle to back of the coach near the rear wheels where the cross brace goes across which is visible from inside the rear compartments. The cross brace which looks like a somewhat corrugated panel tends to crack where it goes over the frame rails causing the entire rear of the coach to sag sometimes creating a hump in the floor inside the coach along with some level of delam in both the sidewalls and often the floor just forward of the hump. You may also note that the wall between the salon and the master bedroom may be pressing more tightly against the ceiling when this starts to occur.
Anyone considering one of these coaches from the 1990's before they came out with the wide body models really needs to inspect this structural member in the basement compartment with a very bright light.
