yes, definitely there is a difference, as stated by others here, in running appliances depending on what size trailer you have. the honda 2000 can run ALL the acs in ALL sized casitas as i understand it. however, in the 17 ft, it is reported that it can only run the ac alone, you need to turn off the ac when using things like microwave, hair dryer, etc.. in the 13ft and 16ft trailers, the ac is the smaller friedrich and mounted under the closet. the honda 2000 in my 13ft patriot deluxe easily runs the ac or electric heater i use, depending on weather conditions, as well as microwave, refrigerator and a LED light. i assume this is also true in the 16ft casitas, since the only difference in the 13 and 16ft SD casitas is the 13 ft doesn't have a permanent small side table/seating, so they split the galley to use that space.
bottom line, the honda 2000 runs all the acs in all the trailers. you just need to turn off the ac when using other appliances in the 17 ft size. you'll learn the capacity of your generator when you start using it. living/camping in your trailer will teach you how to use the honda to best advantage, according to your size trailer and power uses.
before i committed to the honda, i camped/travelled for a while, to learn my camping style. when i found that i did, indeed, want a generator, i visited larry gamble. he had a honda 2000, hooked it up to my casita and we experimented. when i saw how easily it ran several major appliances at once without a hiccup, i was convinced and ordered mine. if you know of anyone with the honda, you might try it on your trailer too before purchase. might even be worth renting one. nothing like actually having one connected to your trailer to show you exactly how well it works.
i hope you enjoy your honda as much as i've enjoyed mine. happy camping.
