Personally I don't see any red flags, but I wouldn't buy any trailer without the
title.
You always take your chances when buying used and especially off listings like Craigslist.
This does not mean that they are bad or a stupid thing to do.
I bought the 5th wheel I lived in for the past year off Craigslist and
sold it the same way.
Just pay attention and if a deal seems too good to be true it probably is.
I put a link here just in case someone near enough to look at it and wanted one could be directed to it.
I have no interest in the trailer and I don't know the seller and have not gone to look at it either.
If you are interested go look if not then.......
I didn't mean to start an argument over buying off craigslist. I buy off Craigslist and had been pretty much satisfied.
I also flag the obvious scams for removal.
