Bought this compressor to inflate 75 PSI trailer tires and 70 PSI truck tires. I had previously burned out several cheap Chinese air compressors inflating these tires, so I was somewhat surprised to find the Viair 400P-RV was stamped "made in China" considering the price. So far, so good - I've inflated the tires on my 35' tandem axle stock trailer (4 tires) from 50PSI to 75PSI in about 40 minutes (10 minutes a tire). The air hose extension is VERY handy, since the power cable on this pump is only about 5 feet long. With both air hoses connected, I can easily reach all 4 tires on the trailer. Pump got VERY hot during the inflation process. I've only used it once, so we'll see how long it lasts.
