globetrotter old parts - frig / toilet - sell / dispose?

[sbsmiley2017]

Hi -
I've got a 1965 globetrotter, we're working on improving it
while using it. I'm curious thoughts on whether there is any
demand for parts on the old refrigerator ( the ammonia unit leaked,
so we removed it), and we're replacing the toilet with a composting unit.
If so, where should I post, I'm more interested in supporting reuse than
trying to make any money from them.

should i just take them to the dump or might some other airstream owner
be able to use parts?

I'm also planning on replacing the furnace with a catalytic heater, whereas the heater works, it shuts off after 20 minutes or so, and I just don't feel good about a 50 year old furnace.

So far -
new bed / couch - custom made by wife
univolt replaced with new converter
new water pump, i loved the design of the original though
fantastic fan added
new floor
pull down shades
led bulbs in existing lights
water heater tank had a leak, so had to remove.

Thanks for any thoughts,

Steve
