When we had our trailer, it had a single 13K AC and a microwave oven. I purchased an EU2000 Honda, and it had difficulty starting the AC, but would handle the microwave ok. So if you will have "more" 120vac appliances than that, I would go with either dual EU2000 units or a single Eu3000 unit. Please stay away from those contractor type generators you find at Home Depot/Lowes as they are so loud they'll cause your neighbors to get a mite upset.

PS...By the way, you're asking for "advice" (a noun), but some one can "advise" (verb) you on what to get. These are often misused along with break and brake, to and too, and lose and loose. I'm sure there are plenty others...
