If you are up for spending that kind of money you might as well dig a little deeper and go for the fuel cell that Loozer Cruiser has just fitted (himself). Biggest benefit no noise.
Be interesting to see how much smoke it produces, being 2 stroke.
We had the predecessor the Gasparini which Telair bought the rights to when Gasparini went bust.
They are designed for light use about 100 hours a year. The whole exhaust has to be replaced each service. The Gasparini had problems with its cooling fan fins disintegrating, Admittedly it was at roughly 300 hour intervals. We did 800 hours in 18 months full timing, having replaced 3 cooling fans. Snr Gasparini couldn't believe we just a list of fault codes and hadn't been given the user manual, which stated the recommend use limit.
On showing the dealer the manual on our return he still refused to accept there was a usage limit.
We has originally intended to fit Solar but were talked out of it by them and the guy who fitted our LPG tank, saying solar was no good for the UK, that was in 2008. Snr Gasparini said it was designed to supplement, not replace solar charging.
Smoke was not visible using the recommended fully synthetic oil. However we did notice the smell, not at first but increasingly after the first service.
We had a remote oil filler fitted in the boot, as it was a problem trying to fill the tank lying under the van. We had a remote hours meter fitted also at 300 hours.
At 800hrs the bearing were totally shot (Late 2009) possibly because of the fans disintegrating and causing imbalance. Our dealer replaced the main bearing but couldn't do anything about the crank bearing as they were a sealed unit with the con rod and crankshaft. We went to Italy and when Snr. Gasparini heard our jenny, he called in one of his former employees in and they condemned our unit that we had just paid £700+ for repairs to and between them built a new one from parts left in the factory (early 2010), which cost a further 800 Euro. The company was in liquidation at that point.
We fitted 2 x 130w Solar later that spring and found after that we rarely needed the jenny after that. We sold the van late last year with just under 300 hours on the new jenny.
There are quite a few "Bush generators" lurking around nowadays - standard Bosch alternator of 50 or 80Amps and a Honda 4 stroke motor. Not very quiet, but the charging rate would probably only need 1/3 of the time running that a 20Amp unit would.
The convenience of having LPG as the fuel is a great idea - if you have LPG tank, shame they don't do diesel engines.
The cost of that unit is the killer - how many hours of running the engine would it take to cover the cost - even if you fit a stationary engine running kit (bigger fans that can be turned on manually).
I've come around to solar now being the best way to keep things topped up, 2 x 100Ah batteries plus a 120W solar panel seems to be able to cope with a 12V compressor fridge, led lights, water heater and diesel cooktop. I've had the van parked for 7 days with the fridge running and the batteries still show 13.2V first thing in the morning. Doubling the battery storage would likely mean a couple of weeks without sun and still have viable 12V power.
Its not just producing power, its what consumes it.
When I looked at Efoy, the fuel cost wasn't expensive: it was astronomical. Much more than £2 per kWh.
That Telair unit says it uses 370g per hour and it gives 240 watts. Assuming a refillable LPG supply, that's even more, at around 1.5 kg of LPG per kWh - about £3 per kWh. Plus expensive oil.
Recharging an 85Ah battery from 50% to 100% will take about 70Ah of power, but assume you only take it to 95% that's more like 60Ah.
I very much doubt it gives 15v. If it does, it is defective. The literature says "it starts when the battery is running low (11.9V) and stops when it is full (14.5 V)." That makes good design sense, but won't get the battery anywhere near 100%.
It won't give 20A at 12v: it will give "up to" 20A, presumably at at 11.5v, less at higher voltages. Its rated consumption is 270g/hour but note that the 25A one uses 290g/hour: most of the fuel is not being converted to electricity. Like almost all two-strokes, it is hopelessly inefficient.
The best possible efficency scenario is that it runs flat out giving 12v 20A for 270g per hour. Real world performance will be half as good at best. But assuming it is running at its best, 750KWh is 62,500 Ah at 12v. So that's 3,125 hours of running. So I assume you mean 750Wh: that's 3 hours 8 minutes running, during which it will use £1 worth of bulk LPG or £2 worth of bottled.
Like many, many other people, I have neither Efoy nor Telair and never use campsites or hookup, but can still park up anywhere, so the saving calculation really isn't valid.
I typically stay about 120 nights a year, so my savings calculation would be £0 x 240 over two years: a massive total saving of £0.
By the way, my recollection of Efoy running costs were a bit off.
Nowadays, it seems that they cost £5 per KWH to run, not £2 (which I thought it was when I last looked into them). What I didn't realise is that Efoy power output falls as they age. After 4000 hours it is half what it was when new. I don't know if they use half as much fuel then. If so, it wouldn't matter too much. Does anyone have experience of long-term use of an Efoy?
I am coming round to the idea of a fuel cell (EFOY) If It can be suitably fitted.
Your post convinces me NOT to go for an LPG underslung unit

I know what you’re trying to do I kinda done the same for about a year before I broke out and bought the efoy. Think the realy hard bit is the initial outlay for the equipment and first batch of fuel. Think after that it’s down to how you use it for me it’s just the piece of mind knowing that under any conditions I’ve got it there working away silently in the background.
If you youse a little bit more fuel here and there then it’s obviously doing it’s job. I’m on hook up at house and when moving around batteries are getting charged off engine. It’ll only really need to be used when sitting stationary for two or more days. Must say that I’m impressed by the low noise level and the ease of the installation. But everybody’s needs are different
If you’re gonna go down genny route you can’t get better than a Honda eu 20i I know there more expensive but you can get one from Costco £1050 with a five year warranty that you can return any time over the five year for refund or replacement. I had one for three year took it back got cash in hand think there’s a member got one for sale on here send him a pm hotrats canny remember what he wanted for it but worth a try.
