I have a Yamaha EF2000is inside a custom box, mounted on the frame rail. The box has vents, with covers, that match the generator. I remove the vent covers and run the generator right inside the box. Safe, secure, and protected from weather. I use it primarily for power to a Xantrex inverter/charger that will keep batteries charged up while no idling the truck, and the AC from the generator is passed thru the inverter to take care of all hotel loads in the truck during a rest break. The gen also provides power to a 500w oil pan heater during cold weather. Keeps oil at around 130F and the lower block warm. Easy start of engine after a 10 hr break shut down in cold weather. It can do all of this running at eco low speed, which is very, very quiet. Much less than most APU's. Unless I concentrate, I never notice a sound from it when I am inside the truck. Can hold normal conversation right next to it outside and it is not annoying. And it can do all of this using only about a gallon of gas in a 10 hr break. When closed up with vent covers on, the box just looks like any other tool box on frame. I don't waste any time worrying that it is gravity fed fuel system. It has a dedicated fuel shutoff valve, a shutoff vent valve on the cap, and I shut off the fuel and run the carb dry after each use of the generator, and no one has ever checked and I give no indication to anyone that I have a portable generator. The box is locked when the gen is just stored in it or when it is running. No one ever sees it.

Just my two cents but as a firefighter in a previous life if your using a gas generator please get a fairly inexpensive monoxide detector and put it in your sleeper.

I suppose, if one is running the portable in their cab like the guy did in Arkansas the died recently. My portable is in a custom box enclosure on the frame rail behind the cab. It operates in there. I just remove vent panels on side and back. I get more crap from other truck's louder APU units than I ever get from the portable.

by

Cliff that would be all the more reason to have a cheep detector, even since you are drawing air for the AC into the cab

by

I am not drawing air for the AC into the cab. I don't have it running an AC. I use the generator to keep batteries up (via a shore power hookup for the Xantrex inverter/charger unit) for hotel loads and, in winter, Webasto bunk heater and engine oil pan heater.. I don't have an AC unit on my truck. All this summer, I have only idled the truck a cumulative total of about 12 hrs for AC. For me, it would be a waste to invest in a dedicated AC unit.

That is what I'm doing. I just bought my 6,400 btu window a/c unit from home depot for $159.00. Bought a gas generator for $269.00. Should work great .....as far as enough cold air. Noise ,, well we shall see.

Interstate 5 trucker ,,

I plan to buy one of those frame mount tool boxes then line the inside with particle board to help deaden the sound.

I like that idea of putting the gen. in a sound proof box. Hope it works.

by

instead of particle board google sound proofing foam, should be able to find some high density foam, but make sure it is foam that has fire retardent in it.

by

Sound proofing foam !!!!!! Hey that's an idea. I will give it a try. That's why I'm in this forum. I allways get great ideas from you young whippersnappers.

remember if you put the generator in a box, it needs air to run.just ad some vents .if you goggle generator accesories you can find exhaust extention tubes to run it outside of your box. Im thinking of doing the same thing. find a generator with remote start,idle control,a cover for weather purposes, frame mounted storage box to store gas can ( strapped to inside of box). I think it will work perfect, as far as noise - get one with idle control and that will help. No more noisy than a loud apu.

Personally, I think most APU's are louder and more annoying than a refer unit.

In the summer you could wire in a small exhaust fan in the box to keep air moving around the air cooled engine.

other then that...it all sound great!

by

I run my Yamaha in the box during the summer months occasionally, and I have never had the need for an additional fan to keep air flowing thru for cooling. The back end of the generator is up against the rear vent on the box, and all exhaust and drawn cooling air is shoved out the back. The side vent allows all the cool air in the generator needs. If it didn't work well, my generator would have been fried by now.

blackwood, I asked a question of you on another forum but how do you have your Danby mounted? I have a LG 9000 mounted in my 379's right closet, it gets plenty of air and I have insulated the exhaust tube but it still does not cool enough, I am going to try the Danby this week!

It is on roller wheels and stands between my bunk and the front wall of the sleeper....I don't think 9000 btu unit will do what you want especially if you have a stand up sleeper. Mine is a 12,000 btu and I still zip down the sleeper curtain so I just cool the sleeper. I also removed my truck interior and lined my cab from top to bottom in this silver bubble wrap material like they make sun screens out of and can be bought in a 48" roll at Lowes. It block the radiant heat that comes through the interior panels. I also cut panels to go over my windshields and side glass. I vented my exhaust air out the passenger side vent door and cut a 4" hole in the floor where I piped 4" PVC to the back of the unit and built a box around the air draw for the condenser core. I have a bud that has a KW uni-cab and he runs a 13,000 btu unit that does a good job.

I run a Champion Remote Start generator and a floor heater. While the generator works, mounted directly behind my sleeper, the rain is raising !&&* on it. It now keeps shorting out, the starter just went out on it and the remote start will only shut it off. I have to pull start all the time now. I purchased back in the middle of December 2014. Although it has saved me money, I would definitely put one in a box directly after purchasing one, to save on its useful life. Remote start is definitely a convenience, I hate getting out and starting it.

I'm running the same kind of system but do not know of a portable a/c system that does not have to vent the hot air outside. If you have to vent hot air out side then you will have to manufacture a fresh air draw to your unit. If not it will suck the oxygen out of your truck.

I think it will be loud and I hope you don't park next to me in a truck stop with that lawnmower engine running. Also, how are you going to mount it so it will handle the rough highways of America, won't get ruined due to weather and won't be in your way? There are also rules and regulations of fuel tank mounting/fuel storage on commercial motor vehicles. I am a big fan of battery operated vs. internal combustion "APU's", whether you build it your self or by one like the NITE system.

The portable generators are often noisy- sometimes as loud as a portable air compressor, and while soundproof foam may help, it doesn't always deaden the noise.

The generator should optimally be combined with an AGM battery pack, a reliable non-gravity feed fuel system and remote start so you don't have to run it constantly. I am a huge fan of battery APUs such as NITE, TriPac E and the DIY battery boxes, since they are quieter and do a better job than department store gas gen sets.

I would also recommend getting your cab re-insulated if you can afford it- it'll make a world of difference in terms of the noise level and how comfortable you are, whether you are driving, on duty or sleeping.

by

The other night, I parked next to a truck running a Tri-pac unit. Decided it was the best time to compare sound levels. When I was in my truck, all I could hear was his Tri-pac. When I was outside and standing to the rear of both trucks, standing behind my truck, the Tri-pac on the other truck was nearly twice the noise level of my Yamaha EF2000is generator. My Yamaha is housed in a custom made aluminum tool box, even when running. It has removable vent coverings to allow exhaust and cooling. No insulation whatsoever. But the exhaust and air coming off the engine cooling is right at the rear of the box, so there is no muffling or redirecting of the exhaust right out of the generator into the open.

The box it is housed in is frame mounted and very secure. Not going anywhere. I can run the generator, out of the weather, and secure from theft. And at 1 gallon an hour fuel use, I don't need external tanks and other stuff to keep it running for a break period.

by

Cliff I like the sounds of your setup. Got any pics? Where did you get the Yamaha? I agree the Tri-pac is loud. I was parked next to one two nights ago. The fan or generator kept turning on and off causing the engine speed to go up and down. Pretty annoying.

by

I got the Yamaha from...

I got the box from KSH Marine. They have the box as it is setup on my semi truck in their gallery of photos. Scroll down page to custom boxes and you will see the box on my red frame rail on my Freightliner. First pic shows it open and slots open and another pic further down shows it all locked up and slots covered. They say it was a Honda, but it really is a Yamaha in the box. Generator can run in box with slots open and lid closed, protected from weather and theft. I have over 300 hrs on the Yamaha running in that box.
