If I had a step that old I’d keep it. It can’t possibly owe you money at this point, and it would definitely be a handy trailer just to have in the yard. I generally don’t sell off my old towed units. I keep them for rentals. So far I’ve been able to use the asset to secure financing on the replacement. I crank way more than the financing charges on the higher no trade-in principal of the replacement out of them in rental revenue. Don’t know your situation, just saying what works for me.
No it doesn't owe me anything. Just sitting their doing nothing. You make some good points. Especially (asset)securing financing on something else. Never looked at that way. Usually don't buy anything until I have the cash.
