We are looking around at maybe getting a enclosed trailer soon and I was wondering what size generators are you guys using. Looking to get a quiet one that will run lights, a/c or heater, battery chargers, air compressor. Currently have a 2500 Yamaha that is great but it has problems running just a battery charger and air compressor.

I have a Honda 7000 inverter generator. It is mounted on a slide out and is very quiet with more than enough power.Since it is only held in place by two bolts it can also serve double duty as a backup home generator.
The most important thing that I looked for when purchasing a generator was noise. But almost every time I go to the track I end up parking next to a guy that has the loudest generator I've ever heard.
You can't go wrong with a Honda.

For quiet, go with Honda,
but their expensive

Onan has quiet generators if you are looking for a typical RV genset. Hondas are hard to beat as well. Mine is a 5Kw generator and doesn't have any problem running a combination of the items you mentioned. Three years and it has only thrown the breaker once.

This may not be the route that everyone else wants to take, but I got a 4000 watt Onan out of an older motorhome. It is 1800 rpm and extreemly quiet. I got it free by buying a dirty old motor home that would barely run for dirt cheap. Gave it a really good bath, put new plug wires on it, took the generator for myself, and sold the motorhome at a nice profit. Worked for me.

I bought a generac RV genset years ago, brand new. It ruined a couple TV sets while I had it. Turns out the cheaper gensets don't have very good cycles regulation and that was ruining my electronics. You could see the lights get brighter when the load would change. Got rid of it and bought a better genset and my problems went away. Don't buy cheap if you want to run TVs and computers is all I can tell you.

Thanks guys. The main reason I want a quiet one is for multi-day races, instead of getting a hotel I'm just going to sleep in the trailer and I don't want a chainsaw going all night. But I want one that I know will run the things I need while racing too.

I have a older Yamaha 5500 watt 110/220 construction generator mounted on the tongue of my Pace car trailer, it is NOISY, but it works well It has the fuel saver feature, idles until something is turn on or is activated and it is electric start the Honda inverters are a lot quieter though. My motorhome had 4000 watt generator(not a Onan or Generac, it was a Kohler) that would run the air conditioning and everything else at night and never failed us once Lots of option out there Check on line first for new ones and Craigs list for used ones

I'd go Onan, I have an Onan 6300 (motorhome gen) that is quiet runs 1800 RPM but I swaped it out for a 4000 Honda liquid Cooled(motorhome gen), runs at 3600 rpm ...rather have the onan, definitly quieter and more fuel efficient. plus less mantainance

Another vote here for the Onan 4000 they sip fuel and will do what you are wanting to do

honda 6500 inverter here, i have run 2 campers of it, in august. so i know it will run 2 a/c units and acc. it only runs the rpm needed to make how much power you need.

The Hz. ( frequency or cycles ) is entirely contingent on r.p.m. , so if you want to run delicate electronics ( T.V. or computer ) you want one with enough power to not lug down as the load increases.
Figure out your max. electrical load in Watts and multiply by 1.5.
This will give you a baseline for the kw rating you want.
The differences in r.p.m. given above are due to a different winding in the gen set itself and probably have to do with power characteristics of the power plant.
Diesels are optimum for a lot of reasons except cost.........they are a heck of a lot more money.
I like the Honda's because they are extremely quiet , but I know Onan makes very nice units too.
I have a loud , obnoxious one that my Dad gave me , but have worked on these filthy buggers quite a bit..........mostly bigg'uns.

If you want one you can run with out opening the generator door you will need a motor home style generator like mentioned above.

I have one of Honda 3000EUs like shown above, extreamly quiet and will run forever on a tank of gas. While I don't have an AC unit in the trailer they are supposed to be able to run one.

Good Luck,
Bill

Any one that you don't have to drag out the back door and chain to the trailer tounge.

Another 3000EU Honda here. Never any issues with enough power.

Cool thanks guys for all the experienced comments. Hopefully we can find a good one with all the recommendations.
