Default MEP 1800 rpm GASOLINE unit?

I am looking into buying a surplus military generator, they seem heavy duty, feature packed and the price is right. A majority of the units i see are lightly used or lightly used since rebuild (hard to tell). I was wandering if they ever made a 1800 rpm gasoline MEP generator? I prefer gasoline for a few reasons but mainly want to use it on a wood gasifier and all i can see is 3600 rpm screamers which do poorly on wood gas or diesels.
Thoughts? Advice?

I do not know about the MEP series, but Onan did build many gasoline powered 1800 rpm gensets. Unless you enjoy repairing overly complicated controls with unobtanium parts, I'd avoid the military units, just my opinion. If you get lucky you might get a military gen that just needs a battery and fuel, otherwise buy 2 or more units for spare parts.

I have a couple of MEP's and they are over complicated for what they do. I too recommend looking at a two cylinder opposed, 1800 rpm Onan generator. I feel there a lot more parts floating around for the civilian models at a more reasonable price, plus you see parts machines pop up every now and then.

It seems to me the military sets are extremely overpriced, both the machine and all the parts.

I think it is due both to the mystique around them as well as certain companies buying all they can and using that mystique to keep their prices up.

Plus there is nothing about them that is any good, in my opinion. The military tends to buy off-brand stuff in the first place, and keep it an extremely long time, until all the one-off manufacturers are out of business, and give it bad maintenance, until it is all borderline junk before selling it.

The small town where I am from got blessed with 3 old military generators through a gov. grant several years ago. They installed one at the water treatment plant, city hall and fire hall. In 10 years I only saw one actually be useful. They were all plagued with electric issues that were a nightmare to repair due to lack of parts and information. All had over complicated controls and if I remember right they had some type of self destruct setting that if activated would short out and create something even more worthless!! I would stay away from anything "military""

I guess not really applicable because mine are diesels. But I would concur with comments about MEPs being overcomplicated.... And sometimes just stupid! Like using "molex" connectors between gen head and output panel. Has a Baldor head and a Lombardini engine and they use junk connectors? Had to totally rewire using 40 amp eurostyle barrier strips. Not as fast as a molex plug but infinitely more reliable.
Mine also run at 3600, which is hard on a diesel, but when it works it delivers a full 6.5KW from a 9hp. My old kohler runs at 1800 but only pushes 4.5KW from a 16hp.
Had to rewire the fuel cicuit on the diesels, but that was simple. Otherwise just cleaned sand from fuel system (guessed just back from middle east, flushed a LOT of sand out of injector lines.)
Don't know if this would be of any help.

I forget what piece of military equipment we had, its been a few decades, but it had a self destruct feature, and manual had further instructions that if self destruct did not work to shoot it with heavy artillery, if no heavy artillery set it on fire, if no means of setting it on fire, start cutting wires! guess they did not want it falling into enemy hands, but who reads a manual while under fire

The military used a number of Wisconsin MAENLD engines to drive 1800rpm portable generators. I have a few antique Briggs letter series generators that are all 1800rpm. Im afraid all of those generator manufacturers are long gone. A friend of mine has a NOS Homelite generator with a Wisconsin VH4D for power. It is 1800rpm and gorgeous. I wish it were in my collection.

Dalmatiangirl, I remember reading something like that on a plate or sticker too! After working on it for a couple hours I thought finding the biggest bazooka I could and blowing it to heck would be kinda fun!! Lol.

Part I didn't really understand was the DEMIL hoops I had to jump through. This is an old 6.5kw generator. You can walk into a heavy equipment supplier in virtually any country in the work and buy a new model that would do just as well (or better!) but I had to solemnly swear that I wouldn't sell it outside the country or to anybody who might try to smuggle it outside the country..... I could see if it was a cannon. (but they had evdn tighter requirements on those, like thermal lancing them to spagetti) but a generator?
