If you say that you're "never going to mess with it" I expect that means you're looking at an "as-is" sale. I wouldn't be a buyer being so far away but a few questions are in order. Is the trailer included in sale? Is this a standard model or ASK? Has the unit ever run in your possession? My guess if you're not certain if the engine runs & the generator produces power, the unit is standard model & no trailer, then as-is value would be $500-$700. If you could get someone to install the IP & get the unit up & running, something like $2000-$2500 or a little more if you did some marketing. Bottom line, if it were mine, I would get the unit up & running & then sell. Understand if you need to sell quick, then that's what you have to do. Good luck with it.
