Is my generator big enough?

Thanks for all the advice. The reason I can't test it is because the carburetor has been destroyed by this insane ethanol gas (that we are forced to use now days) that has destroyed the carburetors on almost every small engine I own. I refuse to fix them so they can be destroyed again and I just convert them all to run on propane and never have another problem. I have dual 30lb propane bottles on my TT with a good space between them and the trailer, where I plan to mount a generator and run it off of propane. Before I go through all the trouble of converting this 2500 watt Coleman and mounting it I want to make sure it will do the job. This is why I have not tested it yet. I have a 5000 watt Coleman that I converted to run off of Natural Gas as a backup for my house in case of a prolonged power outage, but it is louder then a bulldozer with no muffler and I don't want to use it for my TT.
