Extra Insulating windows.

The end of the story. We listed the trailer on line and were flooded with enquiries. It was a 1992 Wilderness, and an older trailer like that round these parts, but in really good condition will go for $3-4000. Ours had a damaged roof, which I had temporarily repaired, and put in the ad that if you were going to use it for travel, it would have to be done properly. I did say that it would be ideal for a permanent location with a fixed covering for a roof.
Everyone told me that I would be lucky to get anything for it and would have to pay someone to take it away.
We were flooded with enquiries! Not as an RV but as extra accommodation for peoples' kids, parents, grannies etc. House prices and therefore rents, are so expensive here. We sold it for full asking price and the windows for $100. I kept thinking storm windows too, but those normally go on the outside.
Now we have to look for a new one!

I have one TT and a Slide in that I am getting ready to take apart and scrap, talked with a local RV scrap bone yard and ask if they wanted any of the windows, table etc. The guy said he had way to much stuff and anything I had was worthless to him or anyone else unless they has the same unit, he also said scrap prices were in the tank as far as the metal siding an his last comment was "GOOD LUCK GETTING RID OF ANY OF IT"

I think they are called storm windows. They were sold as an option like double pane windows are now. They are worth $0, unless you can find someone with the same model and year trailer as you are selling. You would most likely have to pay to get rid of them. I say this because I have a 5th wheel tailgate for a 2001 chevy pickup, a 5th wheel hitch and misc other junk in my garage that I have tried to sell or give away with no takers.

Yes, of course, the idea is to sell them with the trailer, but only to someone who needs them. It would help if I knew what these were worth, to either get a few more bucks for them or use them as a bargaining chip. I've tried looking them up, but have had no luck. It's difficult when I don't know what they are called!

If they are speciific to the trailer thay should go with the trailer. To find some one who has a trailer, in your area, with matching windows so they can be used successfully will be unusual.
Seems to me the older the trailer the less audience you will have
