My experience with Dynsas APU and Boomers Diesel

The biggest problem with apu's is they are made to fit short trucks with minimal frame space so they have to stack the engine and generator so you get belt drive, so when the ac kicks in there is a big load on the belt, mfgs add capicators to help lessen the load so you end up with more eletronic stuff to fail.
If you nave room a generator with direct couple to the generator is the best and most trouble free, but they won't fit most trucks.
I do know the people at boomer and they are probably the most experienced out there.

 

You are correct Spyder 7723, Cat don't make those engines, they are repainted Perkins. I was at the Rigmaster factory in Toronto, Canada when they first came out, right before Rigmaster either went under or sold out or whatever happened to them back then. But I believe Cat bought out Perkins and they are being run as two different companies, therefore the good quality name each brand has built up don't hurt the other.

 

I got my Dynasys at Cantwell Power in Ft. Worth. They were the only shop l found that offered the OOIDA member $500 discount with a one day installation time. The dealer in Memphis wanted at least two days didn't have time for that.

I went with the gen 2 which has the separate refrigerator style a/c compressor mounted in the cab under my bunk. There have been numerous complaints online about it. Mine arrived with a bad generator and they replaced it before l left. The new Dynasys SL model has the automotive ThermoKing style a/c system and has no generator like the gen 2. Makes it more reliable probably. I only use an inverter so don't need the generator. Might try that system next as it is also $500 less.

The main reason l got the gen 2 is the shore power so l can plug into a power pole and have a/c and heat with no diesel used on my dedicated run. Overall l love the system. The heating system is great as l had a company truck with a bunk heater and it was like a jet engine coming from under the bunk but l still froze in bed. The Dynasys puts warm air out the vents and the digital thermostat kept my bunk area a comfy 70 degrees while parked in 25 degree weather.

I also like the digital touchscreen controller that gives any warning codes, gives you cabin temperature and has settings for timed delay starts, battery voltage starts etc. Seems much better than a TK Evolution's two dials where you need a laptop with their software to check codes or settings.

 

You got either the Rustoleum Rebrand or the Krylon Upgrade.

 

I just bought a 780 as well and was looking at the dynasys. How clean is the install? Did it take long? How is is holding up? I read you had a few glitches but nothing major so far god luck! I have been reading reviews and a lot of people have been saying negative things about it but they are all old posts.

 

That's great to hear thanks for the info. One other question. What is your wheel base and what size tanks do you have. Mine is 229" and 150 gal tanks. Might have to cut down one tank for space. I have just under 17" on the rail to work with on the drivers side
