Wondering if there is a nearby RV recycler that might take it versus sending it to trash or a metal recycler.
How about local Craigslist?
Seems a shame to waste, but I’m not surprised about the shipping. A freight company might be cheaper but inconvenient.
I removed mine, too, but I found an out-of-the-way place to store it for the next owner. Gotta be careful, though… When I was storing the Roadtrek spare holder, I found a couple of items I had removed from a 1993 Subaru wagon I gave away over 13 years ago. Forgot to hand them off!
