Thanx again Max .
I always thought too small would be the problem .
I occasionally run across a HUGE generator (APU more like) from some Commercial building or Govt. tear down project ~ always old yet almost no hours of use, I wondered what I'd do with a power unit that was the size of my little pickup truck .
When I was a Mechanic at LAX, the entire fleet was dual fuel, they decided no more gasoline and didn't bother teaching anyone how the 'carburettors' worked ~ being the new guy I got saddled with the inoperable vehicles (including medium duty trucks and crappy Chevrolet Malibu Police cars) , no help from anyone but I learned a lot really fast .
The oil came out looking like new after 5,000 miles .
They were almost all late 1970's rigs plus a whole buncha Chevy Citations II's ~ good looking cars that were ruined by GM's relentless co$t cutting, they all were junk sad to say .

In the old days, basically there was two choices for a generator. One that runs at 1800 rpm or most that run at 3600 rpms(the screamers). This is the speed needed to obtain 59hz. The 1800's are best, very heavy, very heavy duty, slo speed means longer life and quiet. There are some really good propane units that run at 1800. Propane puts out 10% less horsepower than gasoline, but who cares, slo speed, very quiet and propane lasts forever. Good choice for "end of the worlders' or SDA. Most good diesel units run at 1800, more fuel efficient that gas or propane. Now recently someone invented inverter generators. Changed the whole thinking. Now gas generators "can" be as efficient as diesel under certain situations which would be running small loads. Very quiet, very fuel efficient, slo speed for smaller loads. I dont have one yet but probably will get one to run a 55Amp battery charger that takes about 1100 watts. Then there are the big generator units that run at 1200rpms. I really dont know anything about these but I would love to have a 6 to 10KW diesel that runs at 1200rpms. That would last forever. The good units that run at 1800rpm should last 60,000 hours. I have about 20,000 on my Kubota. One mistake most people make when buying a generator is getting one to big. Do not get one with more power output than you will need(except of course inverter units) especially with diesel as they run best at close to rated output. Its hard to do, but at least do the math and try and come close. Max
