I'm looking at Guardian, did you buy the gas or diesel model, what wattage did you buy and have you had any issues with it? How about maintenance, is it easy to service?

 

my father had one installed when he purchaced his used freightshaker from sharp's (in indiana, they didnt install it, they had an outside joint do it).

installer/dealer, improperly tightened the belts, the generator wasent even straight and had one leg of the generators 3 phase field wired into the buss (took a while to figure that one out!), and they left the exhaust venting under the sleeper...not to mention not tightening the flexpipe :roll:

aside from the ****ty work at the installer it's worked great, found a much better dealer/service joint up in Wisconsin just before the warranty went out. we shoulda spent more for the better controller (with timer/autostart)

since its warranty expired i've been modifying it just a little, it's even better now, 3000+hrs and counting.

now it has:
a highly modified ford escort air intake and filter housing (much quieter and cheaper/easier to find filters)
better exhaust routing (kinda hokey lookin fer now lol)
link belts
car audio sound deadening material (ya'll should try it, works great!)
magnetic sheet for covering the radiator opening (for the colder weather)

currently i'm working on a couple more serious "mods"
a seperate GM 140amp alternator for truck loads only (in addition to the barely functional OE 60amp nipondenso unit)
APU dedicated battery (for starting - charged by the 60amp)
muffler from a 98 buick regal (cheeep, aka free, and quieter lol)
large external fuel filter (screw the damn tiny arse OE unit)

it's far from perfect, and it wasnt installed properly, but it works well enough and thankfully the old man has a son that cant leave anything with an engine alone

 

anyone familiar with Pony Pack? I talked to a driver a while back about the one he had and he loves it......Pony Pack - The Leader in Auxiliary Power Units & Idle Elimination Since 1988

 

That guy has been around for a very long time. I was running West across New Mexico late one afternoon when I passed a pickup in the right lane. The guy got on the radio to tell me I had missed him. I was hauling an aircraft piece for Boeing and he was asking me about it. To make a long story short it turned out to be the owner/inventor of PonyPack. We visited for the next 50 miles into Albuquerque and since it was almost sunset and I had to shut down for the night anyhow he invited me to come over to his facility and look at them. I will have to say this guy was an inventor for sure. He showed me his very first APU, it was a motorcycle less the wheels, tires and seat but eveything else was still there. He would get parked for the night, hop out, kick start the motor, put it in gear, let the clutch out then set the throttle with a friction lock. As I remeber he had it turning a big alternator at the time but I was more in awe at the though of an almost complete motorcycle bolted to the frame. It still had the handlebars to hold the throttle and clutch. The units he was building at that time only provided 12v, A/C and used the water cooling of the motor to heat the trucks cooling system. They were run with a 2 or 3 cylinder diesel motor, I think they were a Perkins motor but that's been 17 or 18 years ago. What really caught my attention was how he had come up with a way to generate more heat in the cooling system, he was circulating water through the muffler to generate more heat and even had a damper type system that would choke the end of the muffler to get it hotter.

I have no idea what he's building now but he's been in longer than most all of them you see advertising now days. And I know he was a driver/owner-operator before he went to producing them so he's been in the trucking thing even longer.

 

Yeah the website says they've been around since 1988. The driver I talked to that had one said it was extremely reliable and efficient. I can not recall for 100% certainty, but I believe he said he paid something like 5k installed.

 

I am familiar with the Pony Pack and one thing is that there are no service centers and it is hard to get anyone to work on them. It is also hard to get parts that are specific to the Pony Pack esspecially the older ones. Service after the sale is not to good either and it is hard to talk to find someone there that knows somthing about the units and can help with problems. Also not to reliable

 

Best, most reliable unit, I have ever had is the Tri Pack. . I have a 148 inch sleeper and it run all the bells and wistles (micro, water heater, convection oven, TV, lights, shower pumps etc.) , with two big inverters. It is the quietest unit around ( don't pi$$ of your neighbors) and runs only when it's batteries are getting low, I have 4 golf cart batteries hooked to it and have never had a low battery warning.

 

Its a single sided service unit, easy to do. Mine is quieter because its inside another insulated box. I'm happy with it. I have 350 hrs on it and it works perfectly.
