Is my generator big enough?
I have have a Coleman 2500 watt generator and I am wondering if it will pull my rooftop AC on my 19ft travel trailer? My rooftop AC is a Duo-Therm Model: 57915-541. It does not say how many watts it...

Hi,
It is almost certainly too small to operate the air conditioner if you intend to run the generator on propane. Output may be reduced by one fifth, so it is now a 2000 (surge) VA generator, not a 2500 (surge) VA unit.
Be aware that output also drops with altitude, so what will work at sea level, won't in the mountains.
This is a good point.
You may be able to set up a crude propane feed before you invest in converting it. It's obviously not the safe way to run any propane system but it can be done for testing.
I just started my 13,500. It's 72 degrees out and it pulled 13 amps at start and settled into a 6 amp draw. Still doesn't give us a starting head pressure figure.
