You see inverter generators with a "thd" percentage rating. what does this one have? also just to clarify if it's shipped in the us it has a 60hz?

All Pulsar Inverters are sub-3% and typically well below that. At this threshold it is insignificant to all but scientific instruments. Yes, of course our inverters output 60Hz, -smile- We are a California company! Ring us up if you'd like to chat: 866.591.8921, we just opened. -Tom

How long of a run time does it get per pound of propane (or per 20lb), and per gallon of gas; for full load and half load? Thanks,

at half load, 4 hours with gasoline, 14 hours with 20lb propane tank

1) does the motor have a steel sleeve in the piston cylinder 2) how will it be shipped. usps or ( ups or fedex) ?

Our preferred carrier for GD400BN is FedEx. I don't know about a cylinder liner. I've been waiting 6 months for one to come back under warranty so I can investigate things like that. So far, the opportunity has not presented. -Tom

I purchased the Wen model 55201 and it works fine.
