Carrier APU on 86" Studio Sleeper rigs

I've had both and have friends with both .
Both units have theyre strong and weak points .
I have a carrier and like that I can run it on start stop or continuos , has its own generater that doesent pull my batteries down ....super reliable kabota engine.
Heat is a little weak under 10 degrees.
Ac rocks .
Very dependable and easy to maintain if you take care of it .
Negatives ...its loud compared to a tk and that generater is about a 1000 bucks when it goes ...parts are pricey.

Tk ...very quite !
Super good heat !
Negatives ..
The evolution units seem to be plagued with cooling system issues .
Fuel pump issues and alternater problems .
Neither unit is perfect but I prefer my carrier.

 

The Evolution’s cooling isn’t as good as the original Tripac.

 

Wonder why the new tri paks are such junk ? ....got a buddy with an evolution that is non stop problems.

 

I should have asked the mechanics before I left last company about the specific issues.

 

Had non stop electrical issues with my carrier for the first 7500 hours so they arnt perfect either .

 

Same with me

 

I think you should talk to another Carrier dealer about installing on a Studio. I've owned one but never had an APU on it. That being said I recently acquired a Western Star 5700XE with a Comfortpro. I like it. I just adjusted the belt today as I could not get it to run a convection oven but it works now. With low heat on too. And I agree, the heat is a little light but I find it will keep up no matter how cold and doesn't dry out the air inside as bad as some.

That being said, I just bought a brand new open box Carrier Transicold Shore Power kit for it on ebay for $400. I had a dealer quote me over $1200 just for the parts.

ComfortPro has been around fur 20 years and maybe longer. Although I believe Carrier did it and then bought it back - could be wrong here - but for me it's the ready availability of parts and service. So that wood makes them the predecessor to TK but that's certainly a viable option. Personally I don't like the TK cause it's an inverter for 120AC.

They're used to be an APU called the Mechron CCS and it was a Kubota Z482 coupled directly on the shaft to a 6.5KW stator. It ran at 3500rpm as opposed to 2800 and that made it almost hum from inside the cab. They gave trucks a good shot and like many APU 's that come and go they found it wasn't profitable amongst the competition. Too bad as it was one of the best configurations I'd ever seen. They went back to serving 7 different militias around the world as they'd been doing since 1940. I still have an old Z482 and stator in my garage. It started over speeding at 10,000h and u don't have any of the components anymore. I should rebuild it and just get a 110V load center and a Chinese genset controller. Maybe when my ComfortPro quits.
