I've never been able to find an aluminum trailer with the factory insulation package. Can anyone direct us to pictures and insulation specifics? My concern is it would be "delicate" and have a tendency to "pick".

If you were going to add insulate to an older trailer, what specific product would you use?

I looked at one several years ago and the insulation on that one appeared to be black "rubbery" expanded foam - not polystyrene foam. I have the same decision to make and will ask Spindelberger to send a sample.
