Generators that can be installed under campervan

[RoadTrek Boy]

Have a look at this site, they are not cheap... they are uk agents for Onan generators

I have a big onan generator for sale. Too big for OP I suspect, but might interest someone!

bit of lateral thinking , if you need all that power for work, "work" should be able to fund a campsite with mains hook up. indeed how many days hookup on campsite could you buy for the cost of an underslung genny , dont forget the cost of fuel repairs and eventual replacement , or the benefit of the other facilities youd get on site.

Dometic is the standard. Not cheap, but excellent. Honda engines, last forever.
Why do you need such a power hungry desktop computer? Laptops have been around for some time now, and are excellent as well as frugal on power.

Because I am doing heavy workloads that even the most expensive laptop can not cope. I am doing photorealistic applications and simulations even that workstation is the minimum for being able to work. So a generator is needed.

I can not be in campsites as I have to be on clients site. I understand that my situation is different and is difficult for someone to understand my workflow.

I think a 600W computer PSU will only draw around 3 Amps @230v so not a high current requirement., how many hours are you working? Phil would be on 1/10 of his generation power for that

I had the dometick generator in my last van great bit of kit was fitted when I bought the van it ran off the lpg had its own exhaust and muffler let it go with the van when i traded it in big mistake . If you have a locker that would fit the Honda iu20 you can buy and fit a muffler and exhaust from the states you can also have it run of the vans lpg System.

Yes, or an iu10 would do

Usually 8 to 10 hours.

when we did equipment installations on clients site the contract included the client was responsible to supply mains electricity capable of running a portable welder from day one.

even now were only doing property maintenance we expect use of a socket for power tools.

to be fair had you given more details in the first post i and others you wouldnt have wasted our time offering you unsuitable alternatives.

Definitely, the quietest generators would be the ones that I would love at times
to install under my rear wheels lol.

Wherever is possible to have electricity hookup they are willing to supply it. That is not always possible and I can not rely on it so a generator is needed.

I would like to comment about the wasted time that you mentioned. Every other alternative mentioned in that topic was enlightening not only to me but also to others and it was not a waste of time.

I don't believe that is true. You can get very powerful laptops. Have you actually checked?

Yes I checked. There is not a laptop with that spec. Also for top tier laptops need a second power supply so you need again 600w in total with less spec that an introductory desktop workstation. Time is crucial when rendering and need the all the available speed for fast results. Also pricing is huge difference top tier laptops need more that 4000. With that money desktop can have two to 3 times more performance in general.

I just want to point out that there is another potential problem here...

The amount of LPG you are going to use.

If you have the workstation and air con running 10 hours per day you could use up to 13.7 litres per day.

Telair TIG 3000 G consumption = 350g per kWh
Air coin + workstation = 2kW per hour
700g LPG = 1.37L per hour
10 hours = 13.7 L per day

It maybe less as the air con will cut in and out and the workstation may not always be running at full load.

So let say 10L per day.

Thats a lot of gas to carry in a 5.4m van unless you intend on refilling every couple of days.

Agree, a gaming laptop with a high end graphics card will deal with just about anything video
based, but of course compactness comes at a price £1500 might be enough. A desktop is
generally better vfm.

Yes it is true I was calculating approximately 11 litres per date when AC unit will be needed and it will need every couple of days refueling.

For sure need a conversion to be able to refill at gas station as it would be cheaper that exchanging tubes.

Rather than trying to build in a gennie , you could mount a box on rear with plenty of insulation , and baffled exhaust duct , built similar to this YouTube to suit a small inverter generator eg Honda 2i . a pair of gaslow 11 kg refillable bottles should sort the fuel supply side.
there are several designs on youtube .

I'm a bit of a gamer, nothing cutting edge but need something with a bit more processing power than most laptops. I replaced my laptop recently and as I spend most of my time in the van, power consumption comes into the equation. I use the laptop not just for gaming but as a general home entertainment centre from television, radio, browsing etc so it's running for a good 8 hours a day. I was stunned to see the power consumption figures on some of the higher end gaming laptops some running at 6-7 amps at 19 volts, which would require a rooftop of solar to run for any period of time. I've had to settle for a lower spec machine with onboard graphics etc, still relatively high due to the 17" screen but I now have a decent mid spec machine that I can keep going with the solar I've got.

I suspect digital willy-waving. I've seen that happen loads of times.
Speed is not vital at all. If you get a computer that is 20% slower, it will still work just as well, but will take a bit longer.
You could maybe buy two or three high end laptops and run them together, each doing part of the job, all at the same time. Between them they'd use less than half as much power you claim to need.
I suspect that you are competely wrong, both about the specification of computer you need and a out how much power it will actually consume.
Perhaps you exaggerate the importance of your task, rather than seek to actually find a solution

I am sorry but you have no idea of what I am doing and you are still commenting on what I need for my workflow and something that is not related to that topic.

In my workflow I am doing raytracing and there is no laptop that can achieve the same performance with a mid desktop Workstation. Laptops that can handle those workloads use desktop parts and they are very expensive. With the same money I can build a monster desktop Workstation. Also in multicore CPUs more than 8 cores are not available in laptops. Another great factor having a system in full load both CPU and GPU in laptops drops performance because in rendering it thermothrottles.

Customers can not wait and pay more because I need to get a slower computer so it's is cheaper to pay the fuel and maintenance for an onboard generator.

I've been in IT long enough to know the signs of digital willy-waving. Technically, you are only partly wrong, but you will never learn how.

Nobody can help you because you don't want a solution..

I would like to thank you for trying to help me but I am working more than 20 years in IT industry and I have plenty of experience with large scale projects. I know exactly what I need as I am doing this for years.

The problem is that you do not know my workflow and you are not aware with raytracing and photorealism applications.
