Verify that your insurance will cover it on a consignment lot. Most of them do not have insurance for non owned vehicles. This is discussed a lot on the RV forums.
I am about ready to load all my gear back in and cancel the ads, it's a great trailer and I am now at a price point that I won't gain anything by selling it. The main reason to try and sale in the first place was to build a shop and know that the trailer is sitting inside I might aswell keep her.
