What makes a generator specifically a "RV" generator?

Or, I suppose it would be more accurate to ask what the difference is between a normal portable generator and one meant to be permanently installed in an RV? Is it just a different frame that it's mounted in/on?

My camper is an old Amerigo truck camper without an on-board generator. My electrical needs would be pretty simple, as I generally don't use AC when camping, and rarely to never go to campgrounds (I have a reservation at one for the Memorial Day weekend as part of an annual 4x4 club run, which is the first time I will have stepped foot inside a camp ground in about 25 years). I've just recently "upgraded" to the truck campers a few years ago after many years of just using a truck bed tent, and even then was using 70's bare bones shell campers (no built in electrical or plumbing).

I really just want something to recharge the house batteries occasionally, a back up plan just in case the truck batteries go flat after sitting for a while out in the middle of nowhere, or the ability to run electrical power equipment if the need to repair one of the 4x4s at camp arises.

Being that my truck has a flat bed on it, I was planning on getting something like a 2K watt generator, and placing it in an underbed storage box for slightly better theft resistance, and to keep it out of the elements.

Can I put something like the Honda EU2000i generator in one of these boxes with the exhaust and intake plumbed outside of the box, along with electrical wiring connected to the camper, and leave it there permanently, or should I be looking at the generators intended to be mounted into an RV for this kind of setup?

    My 2KW Honda is secured to tailgate corner of my truck bed. I have one of those lockable hard folding panels cover for my truck bed.. All is locked up plus the generator has a lock cable secured to the wall of the truck bed. All is out of sight...

    This was the best place for my generator to be... The trailer cord fits just fine and allows me to have the generator for other uses...

    My truck has a bunch of ham radio equipment in it so the generator comes in real handy when I run the truck start battery down...

    I just plug my 10AMP smart mode battery charger into the generator and gets me going in a couple of minutes.

    Being in the bed of the truck is great for powering up a couple of long cords for the house when the power goes off...

    My 2KW generator was purchased back in 2009 I think it was and it still starts on first or second pull on the cord. I think the movement in the back of the truck keep the gas from building up in the tank...

  • I think it's best to keep a portable generator portable and not mount it or contain it in a box. It can be secured with a cable lock and they're made weather resistant, I have the cover that's made for my Yamaha for real heavy rain.
  • I think your needs would be served well by a Honda or Yamaha 2000 but it may be over kill for what you stated above. They are reliable and quite with the benefit of producing true sine current instead of modified sine waves which is nice if you are planning on using it to run sensitive electronics like TVs or computers. They are substantially more expensive then similar wattage "contractor" type gensets.

    The typical onboard gensets that are installed in RVs are produced by OnanCummins are usually 4000 - 7500 watt units that produce true sine wave current. They are built to be installed in closed spaces with minimum air flow and have features like remote start (start stop from within the RV)

    It may be an idea for you to consider a small contractor type genset instead of the Honda or Yamaha 2000s. They can usually be had for $150-$300 and would be powerful enough to run power tools (depending on the tool I suppose). Champion Generators have decent reviews and I know a lot of people that use them.

    Depending on the space and available ventilation - it could be possible for you to mount the genset in a utility box in your flatbed and run an option remote start wire into your camper for added convenience. You would need a genset that has electric start instead of pull start only though for this to work.
  • An rv generator has no exhust and no fuel tank. and usually electric start. I saw a guy take an alum tool box and put 2 honda 2000i's in it . Made what he needed to get proper exhaust and plenty of cooling air into it.
