Another generator thread? yea, want your ideas, please?

My 2019 Montana High Country 5er came without a generator. There is space in the front storage for one of those Cummins Onan RV Generators, which right now, works as a great space to haul fire wood. I'm seriously considering getting a generator, in preparation for On-the-road full timing in the next 21 months. Right now, I'm preparing EVERYTHING to make that happen. I believe in being prepared, and the idea of finding ourselves in a boondocking situation is a real possibility. Face it, my wife likes electricity.

So, a generator is on the horizon. So, I'm tossing a few questions out there, and of course, in the end, the decision will be mine. But maybe your experiences will give me things to think about.

So...for starters?

1. Does anyone have one of the Cummins generators. If so, was it worth the $4000 price tag.

2. What's your preference? Gas, diesel, or propane run? I like the idea of the propane run version, and not having to deal with gas cans and such. Thoughts here please?

3. If you have a generator and not the on-board Cummins version, (more like the Honda version), what should you look for when making a choice. My 5er is 50 amp, has 2 air conditioners and a residential refrigerator. I have run on 30 amp hook-ups with no issues, just have to revert back to the former 30 amp days and monitor power management.

4. Do these generators support a 50 amp RV? Or are they 30 amp?

5. I don't understand using Honda style generators in "parallel", using more than one at a time. Why do you do this?

6. If you currently have a generator, and use it consistently, why did you pick the brand, size, style you did?

7. At this point in time, price is not an issue. It might be when it comes down to the actual purchase, but not right now.

8. Anything else I need to consider when purchasing a generator, other than "theft" for the portable units?

Any input, greatly appreciated.

Thanks.
  • Well you can forget about no hook up camping, which is not just boondocking, but also state and federal parks which commonly lack electrical hookups. You'd need a massive battery bank.
  • Two of any inverter generator would be my choice. Cheaper, only one needed many times, lighter...
  • My refrigerator is an all electric residential refrigerator. When traveling, it runs off an inverter, off the battery. So far, it's done great ... although I am hitched to the truck. It did keep ice cream frozen almost 10 hours when we hit a motel once last winter and I forgot to turn the inverter on. We had no shore power in the camper that night.
  • We just use a portable gen set

    5. I don't understand using Honda style generators in "parallel", using more than one at a time. Why do you do this?

    It is done to increase the power output of the generators. Chaining two 2 KW gens together will give something around 3.5 KW +/-. This is done using a parallel kit which is just some wiring and plugs. Not only Honda/Yamaha gens can do this other companies also make gens that can do it. Champion for one. The usual reason it is done is to run the a/c for which 2 KW is marginal.

    6. If you currently have a generator, and use it consistently, why did you pick the brand, size, style you did?

    We have a Champion 3500/4000 inverter gen. We bought it since it is: quiet as a Honda, costs about 1/4 of what a Honda does, has run flawlessly for a year for us. Starts on the first pull most of the time.

    7. At this point in time, price is not an issue. It might be when it comes down to the actual purchase, but not right now.

    8. Anything else I need to consider when purchasing a generator, other than "theft" for the portable units?

    Number one get an inverter generator (they make pure sine wave power), non inverter gens can sometimes damage electronics, some electronics refuse to operate on that power. I have a battery backup that refuses to use that kind of power for example. And they don't conserve gas the way an inverter gen does.

    as for security:

    Well we have one of those wire rack platforms hanging off the rear hitch receiver. I got a substantial chain (probably 1/4 or 5/16 inch links) and chain the generator and the 5 gallon gas can to the trailer. If someone wants to swipe it it will take much more than a small set of bolt cutters. If you use a cable then that small bolt cutter will cut that cable.

    That being said we have never had anything stolen in 25 years of camping. But we do not camp near major cities, period.

    A prime consideration IMO is getting good batteries, we bought a set of 2 Trojan 6V golf cart batteries, wired in parallel to give 12V, that gives you more amp hours of power than a 12V battery does. And they really are deep cycle, the 12V 'deep cycle' batteries are not, running them too low will damage those batteries. Trojans are expensive.

    So we do boondock some, and we never actually ran the battery bank out of power. I only ran the gen once in ND because it was hot and we wanted to run the a/c for 4 or 5 hours. Until the sun set.

    Let me also warn you that most campground have quiet hours that start at 7 or 8 PM and run until morning. You will not be able to run that generator during quiet hours.

    As for gas vs propane, it's a lot easier to find a place to buy gas than it is to find a propane refill station. Not to say that they are rare but they are no where as common as gas stations. Many campgrounds refill propane. But if you run that generator a lot off propane you will be getting refills frequently.
  • I read lots of posts that running the air conditioner will use a lot of propane. Think about petrol if you plan to run the air much. Make sure you are pricing the right Onan size if you expect to run 2x A/C + microwave, fridge etc.

    I primarily use solar. If I want air I am looking for utility power. I carry a small portable propane generator if I get in a pinch with no sun. Too small to run the air. Residential fridge would need a large solar array or supplement with small generator.

    Running a pair of Hondas is just a matter of connecting the parallel cables and pulling the rope. With Honda you can also get an extended run fuel tank.
  • Using two Hondas is easier on the back than one big unit.

    Tell us what you want to run with the generator. Multiple ACs? Is your refrigerator able to run on propane?
  • I have an Onan 4k genset. Onans are pretty good units. It is in MH. It is a gas rig with only one AC units on 30 amp system.
    However, for a trailer I would think about a portable genset in the TV.
