<p>[QUOTE=&quot;femalecdla, post: 12203476, member: 209405&quot;]Do yourself a favor and stay away from this APU. Do not believe all the marketing hype that they put out years ago or even recently. Their APU’s are paper weights. </p><p><br /></p><p>I’m not one to love idling my truck. I purchased the Dynasys APU gen 3 only to arrive at the shop to be told they didn’t have the actual gen 3 in stock. This was after I was told the shop had the unit in stock and I actually paid for the unit. 1 day before my install, I get a call from the install shop apologizing that they in fact didn’t have the unit in stock. That should have been my clue to ask for a refund and save up for a ThermoKing. But I ignored all the clues and asked the install shop what they actually had in stock. They tell me that they had a Dynasys but it didn’t have a generator in it. It also costed $2,000 more than the gen 3. So, I paid the extra $2,000. </p><p><br /></p><p>The very night that they installed the unit, I started having problems. I couldn’t keep the unit in auto mode because it would stop working. The install shop pulled me back in the next day. They did some work and told me everything was good to go. But I still couldn’t put the unit in auto mode or it would stop working. I called Dynasys customer support and was told to just use the manual mode and the unit has a Kobota engine so they are built to last. The customer support representative told me that it’s actually better for the engine to stay in manual mode rather than auto mode because the auto mode starts and stops the engine which is bad for this unit. </p><p><br /></p><p>Everything worked great up until I reached 4600 hours, about a year and three months after purchase. The engine will no longer start. It cranks but won’t start. I went back to the install shop which they said I needed a part that was not in stock. But they had a fix for it. The fix worked for about three days and the unit wouldn’t start again. </p><p><br /></p><p>Since this happened in the middle of Arizona dead in the summer, I needed an APU or idle my truck. There are no shops on the West Coast and each shop listed on their website told me that they have so much issues with the Dynasys APU’s and no customer support, they have stopped working on Dynasys APU’s. Don’t take my word for it, call the dealers listed on their website. So, that left me with only 2 dealers that I know for sure still service this paper weight on my truck. </p><p><br /></p><p>I get back to the East Coast in Florida and drop my load and head straight to the shop. There was a Hurricane IAN coming so they couldn’t take the time to repair my unit. 2 days and still no start. I left after paying for the labor with a broken APU the same as I came into the shop. </p><p><br /></p><p>Frustrated, I left headed to the other service shop, the one that installed it in the first place. But, I decided to turn around and go back to Florida. I called Dynasys customer support and they said it needed a part. I paid the other service shop to next day air mail the part to Florida. They put the new part on and still no start. </p><p><br /></p><p>Furious now, I called Dynasys customer support and they agreed to cover the costs of repairs once I got to install shop in Ohio. They worked on it for 2 days. Finally, the unit worked for another 2 days. But then it stopped working and still will only crank but won’t start. I called Dynasys customer support line again and they basically said there was nothing else they could do to fix the unit. Both service shops are at a lost what could be the issue. </p><p><br /></p><p>The moral of my story is stick with an APU unit that is well known and can be serviced in any state. ThermoKing’s are expensive but they last way longer than one year and they can be serviced in any state. ThermoKing also cares about their brand. I’m out of $12,000 not including maintenance and repair costs. Dynasys reputation is so poor that I can’t even sell this unit for half the price I paid for it. I only had one offer for $1,500. Try buying a used ThermoKing for $1,500. Not going to happen. Save your money and don’t waste it on these second hand APU companies that draw you in with marketing ploys that claim they have a better product than ThermoKing. Unless you’re mechanical and know how to fix diesel engines, just stay away from the others.[/QUOTE]</p><p><br /></p>
