On Board Generator vs Portable Generator

We are researching the purchase of a new toy hauler. And one of the options we are struggling with is whether or not to go with a portable generator, or the factory installed generator. Your opinions and experience on this subject would be greatly appreciated. Thank you!

Depends on where you are camping too. How often are you running it? Cold weather camping?

Good point TomG2. Money is a definite factor. But, as others have pointed out, convenience is important too. I've had two on board Onan generators, and been very happy with them. I've also had a Generac, that I had nothing but problems with, and eventually had to replace. The initial expense of a large Onan, and the possible cost of repairs down the road, are another factor to consider. I also think about, how much the absence of a on board generator would affect the resale value, and resale possibilities down the road.

I have been using twin Honda EU2000's paralleled for years with no issues... I now have an Onan 6.5 and hands down it is better !!

The Honda's did fine, but i could not run both ac's... i had to hook them together... if running for a while, get the extended run tank out and hooked up...

Now i just press a button , No comparison !!!

What is the difference in cost when it comes time to repair or replace the built in unit compared to a portable model of similar output. Or is money not a factor in the decision?

I use both depending on the situation. I have a built in 5500 onan in my toy hauler. A 6500 in my motorhome(for sale) and a 2000 watt yamaha.

I haven't used a built-in, so I can't speak to any possible downsides of those. I currently have a 2000w portable inverter generator, and have to concern myself with theft and rain. I would rather not have to do that.

built in YES. Ready at a minutes notice and don't have to worry about getting stolen.

I thought all toy haulers came with a generator? Never seen one without one. My previous 5th wheel came with a generator so I've never been without one. I wouldn't want the hassle of a portable one with the added ability for it to be stolen. Mine has it's own 30 gallon gas tank. Most all toy haulers have gas powered generators while the 5th wheels are propane powered.

Perfectly happy with my Honda 2000. Rarely have the desire for A/C when dry camping. Hate listening to the neighbours built in screaming away even though little of the power it is producing is being used. The portable inverter genny runs at whatever speed it needs to for the power needed.

Hate the exhaust smell, in tight spots like event camping, from the neighbours built in. Very few have one of those snorkel exhaust thinghys.

Now, if you are going remote dry camping or your idea of event dry camping in something noisy like NASCAR, the go for the built in onboard genny.

Which ever you choose, make sure you have a working carbon monoxide detector on board. Here today, no wake up tomorrow.

I personally would not own a Toyhauler without a built-in Onan. Even if you decide to go the portable I would make sure it had a generator ready pkg otherwise you'll take a hit when you sell.

The guys with the built-in generators usually get a free pass when they run their generator at the places with generator run time restrictions in place...

I have the portable and I usually get caught within a few minutes of the quiet time. Gets turned in by the neighbor folks in a heart beat.

The guy next to me with his $300K motorhome with built-in generator is running way up into the evening... He's probably the one that turned me in haha...

Dual standard or money talks or something like that haha...
