This is a cat Generator on top of a 200 gallon diesel tank Trailor. It was left on our property (ranch) by the last rancher who leased our land '15 plus yrs. ago'' couple yrs ago I & a mechanic friend put a little TLC into it , IE.. big new battery, starter rebuilt , new solenoid drained fuel system , drained oil 15w/40 drained all old fuel out of the trailer and filled it back up since then. We got the engine fired up after knocking off a few mud Dobers which are now back up in there inside generator enclosure, power washed it got it running and looking good.. It's a caterpillar... There's 1 problem, we can't get it to put out any electricity and this generator is one of those big ones that run a hospital.. I didn't spend anything else on it.. It is a big powerful engine that runs good with a charged battery...Its dead.. so its as is... Just come and get it, at least a 1 ton 4 x 4 truck or bigger... It has not been started for at least a year.. just sitting.. 1 tire has a slow leak.. I got air. Been sitting awhile... Tail lights and wiring I doubt is any good either...2 3/8 ball... defiantly worth 6000.. but I'm flexible.. so please call me..(serious callers only)... the hitch has a busted latch, but it will drop down onto a ball.
