This compressor delivers fast air at continuous operation 100% duty cycle unit is capable of pressures up to 150 PSI continuously without the need to be rested, unlike lower priced compressors that can leave you stranded. I have gone through several other compressors that take long time periods to get your tires up to pressure, if the ever get there without melting down. I have a F350 that we pull a 5th wheel with Class D tires inflate to 80 Lbs. PSI. Many of those compressors fail before achieving that pressure. This is quality equipment right down to the accessories. The connectors, gauges, and inflation gun are my favorites because of quality, ease of use, and accuracy. It's great for my 5th wheel and with the hose I can reach all my tires on the tow vehicle as well as the 5th wheel without  pause.  I often go to my jeep or truck to use these tools instead of the many I have in my shop. Two minor issues Is the rubber shocks on the sand plate I feel should be metal springs because I picture them rotting but they do work very well . Then the oddly shaped  bag is nice, but it's a bag leaving the unit somewhat vulnerable to damage,  from things being placed on top of it in loading, and difficult to pack because of its shape. I know this can happen because my first unit came freight damaged with the quick connector cracked off. A hard case would be more bulky but may be a better alternative and easier to find a place to pack. I have come up with my own fixes to both of those issues. These is a wise investment, and recommend it to 4X4 enthusiasts, and RV'ers.  I hope to share with you my most recent experience (below) how it save me the agony of criticism from my wife and gained approval of my buying my toys. I hope the review was helpful and enjoyable.Here's the scenario. We were out camping in Mammoth lakes, CA with our 5th wheel. One day while we were on a side trip leaving the 5th wheel at camp we visited some of the local natural sites. This day in particular was Obsidian Dome (a huge dome of Volcanic glass). After driving around it we started to explore the adjacent roads. We went to several beautiful areas on good roads with no incident. The final excursion (somehow it's always the last one) we venture down a road leading across the edge of a meadow into some trees.  The road started to get rougher and narrower and felt it prudent to reverse direction in a campward conclusion. The road was to narrow to turn so I back down several hundred feet to a spot I could make a multiple "Y" turn in my 4x4 `02' F350 super cab that has a lousy turn radius. It really becomes more of a "W+" maneuver.  I find a nice clear space and backed up into it successfully and went forward into the opposing bank in effort to re back to change my angle back down the road. Now remember where I am (volcanic region with pumice for soil) and what I am driving ( a monster rv hauling truck with highway tire pressure of 80 lbs PSI). That's the turnaround point comes as well as the wedded bliss starts to crumble, because my front tires sink into 12" of pumice fluff. But no problem I have a Hilift jack and the 4x4 kit (bought at Amazon .COM LLC), but I'm short on chain. So I add a old tow strap into the mix and start to pull out of the holes my tires were spinning in. My wife saw the light at the end of the tunnel and the sun about ready to go behind the mountain. She actually said she would never complain about "My toys I buy".  That lasted for about 5 minutes when the old strap stitching at the hook gave away and the truck rolled back into it's original position. From experience I swiftly said That's OK I can still fix this. I said We need to rethink this. She started mumbling something like she would go to the Bahamas next year. I couldn't help thinking my tire pressure was an issue here so I break out the Viair compressor (bought at Amazon .COM LLC),. She said whats that?, another toy?  I installed the tire valve stem deflators (bought at Amazon .COM LLC),  and took the pressure to 15 lbs.  This is a piece of advice: get her busy picking up bark and stuff to add body to the pumice or sand.  Eureka!  SCORE! The trick did the job and I kept my smartest man in the world status with my lovely red head (the dogs never lost the faith). We got turned around without calling AAA before dark and proceeded down the road to a junction with very good base. Now this is where the compressor comes in. Now I need to reflate the tires to Highway pressure. My experience with other compressors was they will take an immense time to refill and melt down after lengthily operation.  This compressor promises contrary to that and delivers. In fact It seemed to fill just as fast as my 3 hp compressor in my shop. On the same road trip my air lift bag compressor melted down and I was able to manually use this one to fill my bags. Turns out my wife approved the purchases and we will be returning to Mammoth next year. &#61514;
