Your 2800 watt generator will make about 2500 watts using propane. I had a propane Onan generator for 9 years and never experienced the problems that "mexicowander" describes. It was trouble free all of these years.
This is a typical quote often repeated. I can tell you first hand from test that I can produce full power from my Yamaha on Natural Gas and Propane. The small Yamaha generators have enough excess HP to over come the lost of power.
I suggest you go here, these folks are approved by Yamaha to convert their generators

"
Is there any power loss when operating on alternative fuels?
No, we have never had a single unit show a loss of power on alternate fuel. Though lower gallon-to-gallon in BTU content, sometimes they perform even better than running on gasoline (see also fuel consumption). The engine regulator we install has an external fuel mixture adjuster that can be turned with your fingers and can be fine-tuned to your elevation and to the fuel supply connected. That's why we include the Engine Hour/Tachometer Meter with every generator. You can watch the engine rpm output while turning the mixture adjuster for peak performance and high efficiency. This allows full control over the fuel mixture no matter what elevation. Unlike operating on gasoline where the carburetor is a fixed jet and it can not be adjusted only replaced. This is a big advantage that allows the engine to be reset at anytime. Engines would not use the same fuel mixture in different areas especially as diverse as say Florida would be to Colorado. Unlike gasoline, setting the mixture lean on alternative fuel is cool running, clean burning and efficient."
