When it comes to a motorhome, tires are your foundation. I found this VIAIR device to be correct and fairly well packaged. It works great and inflates RV tires well. The 60ft coiled hose is great and you only need 30ft for large RVs. The battery terminals are fairly well made and make for a solid connection. The automatic function is handy as the compressor only runs when the tires blow out, eliminating the need to move the compressor from tire to tire. Generally, 100% duty cycle is what you need. Why would you need a shorter duty cycle when you have no idea how long it will take to bleed all the tires? This only applies to maximum pressures, they are all like that. If you have a blown tire seal, no air compressor you can buy will help. So you still need roadside assistance. However, by maintaining proper tire pressure plus or minus a few pounds, you'll keep your RV safe and protect your tires from wearing out too quickly. Get one and be safe.
