Insulation in Kingston trailers

I’m looking at an 06 Kingston Belvedere that’s in great shape. New tires and very little rust. Very clean as well. Steel frame with aluminum skin. Wondering how insulted Kingston’s of this age are? Also how much do you think is a fair asking price?

If you can see the interior frame structure inside the trailer, it is not insulated at all. Most Kingstons are not, but in order to do it the insulation must go underneath sheeting on the inside, so if you don’t have that it’s not insulated.

I don’t think most trailers without living quarters are. Price will depend a lot on the size/ configuration/ condition (and your location), but they are generally quality trailers and hold their value well. I have a friend who bought a older 2H BP Kingston with dressing room for about $4k recently.
