You may be able to run on one Honda 2000. We did it on our previous TT, BUT we had to turn everything else off, including the converter. We couldn't even run a small fan. So yes it can be done but a pair of 2000s would give you almost the same power as a 30 amp hook-up, so you could run the AC and a majority of other items.

You really need 3000 watts or 3kW minimum. The pair of Honda EU2000i with parallel kit work well and a pretty much sip the fuel. Check Wise Equipment for a super price on the pair.
Honda Super Quiet EU2000i and EU2000i Companion Portable RV Generator

If you want just one 3kW generator, the Honda EU3000i is good, but weighs more in a single lift. The pair of 2kW generators weigh about 50# each which is manageable.

You can also get a 6 gallon external extended run tank.

A lot of RVers will go with the cheaper Kipor, but service and dealers are harder to find.

Most of all, do not buy the cheaper contractor model if you value you fellow campers. For each 3 dBa increase in sound level, the sound power is doubled. So a 9dBa increase in sound is 8 times the sound power level.

I use my Honda EU 2000i generators for my amateur radios as well as the RV.

I always go a bit larger on a generator then you think you need.. The smallest I would go with is a Honda 3000. That way you can watch your movie with the AC and pop the popcorn... maybe.

I have had good service from my Boliy generator
. When you read the specs, it bests a Honda 3000 in all categories, at 2/3 the cost. If you use the search feature here you will locate past threads with comments and thoughts about this light-weight(for the size) generator. Mine powers our 15.5 BTU heat pump with power to spare.

My wife's grooming van has an 8500. It will pull the roof AC on high (a 15,000 btu), the industrial canine hair dryer, lights and vacuum cleaner, all at the same time. If you want to live in the trailer without blowing breakers you're gonna need 4000 watts or more. The problem with that is that most generators in that range are contractor grade generators and are loud. You're neighbors wont put up with it.

Honda makes very nice generators, as does Yamaha. They are expensive. The 2000 will just barely pull the AC. A 3000 will pull the AC, lights, etc.. But, add one more thing and you're gonna pop a breaker on the generator. That's why, other than on some camper vans, the minimum generator size you will find is 4000. And, it's a good quality like Onan that will pull the full 4000 watts (4kw). Two 2000s linked together will do the trick. The price isn't horrible. You can link two of them together for around 2000 bucks.

I wish that more companies made and sold quiet generators.

I was up in Cherokee a couple of years ago and I saw a travel trailer that a guy had mounted a generator to the tongue, over the LP tanks. It was a cheap contractor grade generator. Actually, I see this fairly regularly. But, you can't really get by with that in a campground. Those cheaper generators are just too loud. They make good power, but they are loud.

I finally got around to firing up the unused Kipor 3000, 'true' Sine Wave Genny that was 'thrown in' with the lil used TT I bought earlier this year. VERY quiet, and this ex-Sound Engineer believes their spec of ~58 dB at 'low' loads. We were going over the Genny in the rear Hatch area of my SUV, and it was near Ear-level to boot.

More importantly, the experienced fellow at the Shop I was at had good things to say about Kipor [pronounced 'Kipper']. He almost never sees them for repair. Very reliable. On his 'real life' Test Bench Load, he said he was amazed to see the 3,000 Watt Genny crank out 4,000 Watts w/o a sweat or output Voltage drop. Now, THAT'S conservative Specsmanship.

He also gave me the tip to Choke any Genny for a few seconds only, tops. The way a lil Spring on the Choke Line is configured, I can add a +12 VDC Solenoid that energizes only on Key 'Start' position by pulling on this Carb Valve Spring/Cable 1/4" or so. That Geek tweak, along with a Radio-controlled Start Switch I can jimmy up myself, and I'll have a Homeboy Remote Start Genny!

A pal just gave me nice Gas Tank w/Hand Pump he used in his lil Boat. I can SAFELY tee on that Tank, via a 3 way Shutoff Valve used on ATVs. So, I can also extend run time with a 2nd Tank. The trick I know from working with paralleled Water Cisterns is to keep both Tanks at the same horizontal level AND ensure everything is intrinsically safe and engineered as fool-proof. This way, Tanks can't flood each other by Gravity differential.

The 'bad news: sucker weighs about 125 lbs. So, I mounted the never-mounted Wheels and will enjoy the 'free' Genny. It's stout enough for House duty backup during Grid outages. I'll sell the very noisy, lightly-used 4,500 Generac I have.

We Boondock, but the n/c Genny price as part of the TT deal can't be beat!

Kipor 3000 Genny

My almost-new, 13,500 BTU TT A/C starts fine w/o tripping the TT 15 Amp 120 VAC Breaker. My Ear can hear the 'gentle' start up. That means it initially draws less than 1,800 Watts [~15 Amps x 120 VAC]. My new, 'obsolete' Carrier RV AC appears to have a 'Soft Start' Switch built in; the key. Without Soft Start, A/C start-up current inrush surges tax Shore or Genny Power. Retrofit A/C Soft Start Kits were <$20- at Amazon when I looked a few months ago.

I have the Champion 4000 watt (3500 continuous watts) portable generator as a back up for my 5ver. It runs great, it's quite, and is very reasonable at $300. You can get it at www.campingworld.com. I can run my 15,000 btu a/c, lights, etc. It has a built in 30amp rv hook up and does what I need it to.

I recently purchased the dual Honda eu2000 setup for my 35' K-Z. The meter shows the A/C is pulling 1600 watts, which is about the max. continuous output for one generator, so there's nothing left for other equipment with only one genny. I also learned that when the generator's eco-throttle switches are on (slow mode), the compressor start up surge overloads them before they get up to speed. I let them run full bore and turn on the A/C using the manual setting so it doesn't cycle on it's own. After it's running, I switch on the eco-throttles to conserve fuel. With the windows shut and the A/C fan running, there's no vibration and very little noise. It's not nearly as convienent as an on-board system, but I now have two 2000 watt portable generators for emergency power at the bricks and mortar home.

Have a Kipor 2000 watt- will run everything (microwave included) but the AC. The AC says minimum 2400 watts. Would go with no less than 3000 watts if expecting to use the AC. HTH.
