I have a 19 ft. Palomino G-215 Ultra Lite TT with a 15,000 BTU AC and am looking to buy a portable generator to take with camping. What size generator will I need? In looking at the Honda 2000 and 3000 models, neither say they will power that size of an AC. If I go larger, then the generators weigh so much seems like it will be hard to transport both on the road and at campsite. Any suggestions?

I would try to find a 3000 honda to try out first. see if it will run that big a/c. Are you sure it's a 15K? most 19 ft TT only have a 13.5K a/c. you have to think of other things in the TT also, not just the a/c. add up all the 120v items and add the amps watts needed to run them all at once and then add 25% more watts and that is what you need.

I think you could parallel two of the Honda2 2000's and be OK.

A single Honda 2000i probably won't run the AC but will run everything else. A single Yamaha 2400 can run a 13500BTU AC, my brother does it on his 5er.
So, either a single Yamaha, dual Honda 2000i's, or a Honda 3000 would be your choices with name-brand units.
If you can forgo the AC a single Honda would do, and it's lighter than a 3000 or Yamaha 2400.

Well this might be great if you need to run your AC and Microwave and etc.. all at the same time, but this would be a waste 95% of the time (specially when the OP is concerned with weight). I would find a gen that will start your AC and use it to run your stuff one at a time (microwave or AC). Two Honda 2000 should be more than enough for your needs (and the nice thing is when you are not in need of the AC you could just use one). As was stated I would check to see if your AC is in fact a 15K (because most in your trailer size would be smaller) and in that case a Yamaha 2400 might work for you.

This is just my opinion but hopefully it helps.

When I first got my RV trailers that was the first thing I wanted to buy was a Generator set to run my air conditioner when camping off the power grid. Right away I found out that most of the public camping locations here on the East side of the US including the Natl Parks etc all had generator run time restrictions in place and I didn't find any public place that would allow me to run my generator after 8PM at night. You being from NC you may run into the same problem as far as being able to run your generator anytime you want to.

With this in mind I decided the best route for me was to beef-up my trailer battery system to run all the 120VAC and 12VDC items we wanted to have "ON" when camping off the power grid and go with the plan we would run silent from our battery bank for the one day/night camping run and then re-charge the battery bank the next morning during the ALLOWED generator run time.

The 2KW Honda EU2000i generator is well suited to do this for me... I will connect the 30A Trailer Shore Power Connector directly to the 2W Honda Generator 120VAC receptacle using a RV30A-15A "dogbone" type 18-inch long adapter and with smart-mode charging technology can re-charge my battery bank to 90% charge state in a short three hour generator run time so that I can do all of this all over again for the next day/night battery run time.

I keep my 2W generator in the tail-gate corner of my truck bed which is secured to inside wall of the truck bed. The truck bed is covered with one of the lockable FOLD-A-COVER folding hard plastic panels which keeps the generator as secure as I can when not using it. I just pull it out onto the dropped tail gate when I need to use it. My generator will go where I go and hopefully this will keep it safe from thief.

i have a honda eu2000 and it runs my 15,000 btu a/c unit, along with a directv receiver and a small led tv.
but if you need to run anything else,.. turn off the a/c.
make sure the fridge, water heater, etc. is all on gas or you will trip the overload…
i should mention, my batteries are not being charged by the inverter...

I had a Honda EU3000. It ran a 13.5k BTU a/c and many other items at the same time (though sometimes it would overload with the a/c and vaccuum).

My new trailer has a 15k BTU a/c. I got rid of the EU3000 and bought 2x Honda EU2000. Parallel, they have no problem running the a/c plus other items at 6000 feet elevation. If you want to run your a/c on one of the EU2000s, you're on the edge. I know people have reported they've done it, but I doubt you can do it at any elevation and you'll probably need a hard start capacitor. (My a/c would not run on a single EU2000 at 6000 ft. I'll try running it on one at +/- sea level on my next trip.)

I like the 2x EU2000 set up more than 1x EU3000 mainly because of weight. The small generators weigh +/- 50lbs each...so they are easy to move around. The EU3000 weights +/- 150lbs. So, if I'm not planning on running the a/c (which is often), I'll just throw one of the 2000s in the truck.

Pros for the EU3000: it is slightly quieter and has a more pleasant sound. Plus I now have two generators to maintain, store, move around, etc., vs. one.

Price wise, 2x 2000 and 1x 3000 are similar.
