    It's possible that the wiring for the fan got unplugged and after a little while begins to run hot no different than any other engine . pull the cover, take a look at it from the fan to the computer. It sounds like it became undone accidentally. If you can get to the box for fuses on the unit check them too. If the little mini fuses check them with a tester while it is running. that will tell you if they are all working too.

    This sounds weird but check the water level, check the oil level, Check to make sure the fan is running. Do this by Pulling the cover and holding down the cut off button for the cover. Prime used to put a Zip tie to hold it down so you won't have to hold it down. Check all wiring to make sure nothing came loose for the fan.
    Now next time, when they do the PM, stand there and watch them to make sure they do it right.
    I said check the oil because one time they filled mine up till it was flowing out the dip stick and then did not drain it down to the correct level. Gotta love TA

    The levels are good, fan runs, wiring looks good. Everything I can observe with my limited knowledge looks good. Now it's giving oil pressure errors too and is blowing room temperature air. I give up.

    Everything was FINE before I got a PM. By fine I mean it had been at least eight weeks since I'd been in a shop with an APU problem with is a good streak for a Rigmaster.

    I'm just going to idle until I get yelled at and then probably idle some more.

    What I'd really like to do is learn as much as I can about the thing, like a mechanics level of knowledge, so I can just take care of the #### thing myself.

    Undo the bolts holding it on. At some point your problems will be solved. Signed, a former Rig Master owner.

    You can pull the manual from the Web that is what I did when I had one.

    Anyone here have the new model with the new Kohler Tier 4 engine? Same engine as the TriPac EVO. For $2,000 less and 150 lbs less it is tempting. l also really like how it is self contained and won't have to drill holes in my brand new sleeper to mount a condenser.

    I had also read here the new RM have been working well on severe duty trucks in Australia. Is there any truth to that? Thanks!

    I have one. Belt broke the third week, other than that she runs great. Some false alarms of oil pressure, has lugged at start a few times, but a restart fixes that.

    Have the new model with the Kohler, louder than the tripac & sounds reminiscent of a radial engine. Works except for random times it decides to not work & throws error 4 & 7 engine failure to start/run. Been in shop twice so far & no one has figured it out yet; of course it runs fine when we get to the shop but then like last night after running fine for 8+ hours, it shuts down & won't restart in Dallas...91*F at midnight...currently 112*F...been idling ever since...
