I have a 13,500btu A/C with ducted vents (1997 Thor). We are in Loveland, Colorado, altitude about 5,200 ft. I hooked my Honda EU2000i to it for 1 hr. Outside temp was 80deg, inside was 84deg. I turned off all breakers except the A/C one. After the 1 hour the inside temp was down to 73 deg. I am going to try it again tomorrow. It is to get close to 90deg during the day.

OK, but what is your question? The generator started the unit, (surprise) so its fine. So for how fast and how far it will pull down the inside temperature depend on a lot of variables, but it will never get it down more than 15* below ambient outside air temp, its doing about all it can.
As long as the generator will start it, a larger one wont make it cool more or faster.

In a test, I ran my 15,000 AC off my Honda 2000 in Death Valley for about 45 minutes. It really strained at the startup, but as soon as it recovered, 5 seconds or so, it handled the AC without any problems. Understand that Death Valley is about 300 ft BELOW sea level. I don't think it would start my 5,000 AC at anthing about 2 or 3 thousand feet.

No question, just showing that with this 1st try it ran the A/C for an hour before I shut it down. Is the tech issue section just for questions? Maybe I posted it in the wrong place. There have been questions on the forum as to weather a Honda EU2000I would run a 13,500btu A/C. I have one, so I am doing (I think) a service to those who asked the questions. So it started the unit, surprised me also. I will see if it gets the temp more than 15deg lower than the outside temp. No offense, but I am not going to take your word for it. It may not even run the A/C when it gets over 90deg, we'll see. I know a larger generator won't cool any more or faster (120 volts is 120 volts).
I fully understood that with all the talk about the 2000 watt generators not handling 13, 500 BTU airs...that your post was to verify to everyone that it works! Now..lets Dismiss this notion about Cooling......Your roof airs are more than capable of cooling below 15 degree's of the outside Temp. I keep reading this whenever talk about the effectiveness of Air conditioners comes up. Even though the temp outside has an effect on the cooling capability...Ive been in 117 degree heat and Ive had it down in the high 60's and low 70's in the motorhome....Much better than 15 degree's below outside ambient air temp! It all about the intake air temp opposed to discharge temp.

Don't be so touche, If you had stated whet your posts intention was, I wouldn't have asked whats the question was.
Your lucky that it started your AC, of course you unloaded the board, (opened all other breakers) including the converter/charger Etc, and that all helps.
And you dont need to take my word for any thing, Ive only worked in this industry for about 35 years.
The amount a particular AC unit will drop the temperature inside, depends on one thing, how fast the AC unit will moving heat to the outside, compared to how fast heat enters the space. And the grater the temperature difference, the faster heat will enter the space.
The variables are many, but If you have 2 AC units but only 50% more space and load, the AC will drop the temp more than 15*. Or a large AC unit on a small space, but in general that's about what RV are designed for.
At some point all systems will ultimately reach there thermal dynamic balance, (incoming BTUs/HR equal the exiting BTUs/HR) and that's as cool as that unit will get that rig on that day. All variables considered.
But dont take my word for it, Google RSES (Refrigeration Service Engineers Society) Ive been a member for 30 years.
Most likely the RV industry doesnt put a lot of engineering in to this topic, they just stick a unit or two on top, and sell it.
Please dont take this as a flaming, that's not my intention, Im just trying to giving you and other reader some facts.
It ran the A/C but what was the voltage output before you turned on the A/C and after it was on. An A/C will run below 108 volts but not for long before you damage the compressor. Your running voltage is more important than if it will run the unit also what about when the A/C cycles off and on again. How high did the voltage go up and then down again.
Don't be so "touche" ???
Kinda like Touche Turtle?
But no big deal, all's cool, Mike!
[I believe you] -
and I got the picture from the title of the thread
that WKAYL was giving us the results of his test.

The only thing your test proves is that it worked once for YOU.
There are MANY variables that can change the results of such a "test"
Just because it worked for you once doesn't mean it will work for others, or for you in a different scenario either.
The bottom line is that a 2000 watt generator will not run a 13500 AC with what most would consider a reasonable degree of reliability.
Remember, TTs have wheels for a reason. They will always be in different locations with different conditions.

The other issue is that if the Honda runs at max or near max load, it should only be for 30 minutes per the manual. I have to believe that running an ac will be pretty close to max.
