Portable air compressor advice is needed
I'd like to purchase a dc powered portable air compressor for my travel trailer, just in case I need to top off the tires while on the road. I already own two other compressors that I prefer to leave...

I went with the Viair 300P, because my trailer tires (at the time) only needed 65psi. We recently changed to a motorhome that has 22.5" tires and needs 95psi. I thought for sure I'd have to buy the 400RV model. But first, I ran a quick experiment. I dropped a tire down to 60psi and then hooked up the 300P. Expecting a struggle, I was surprised that in about 3 minutes, I was at 105psi. I don't suppose I will be changing air pumps!
I'm sure the duty cycle is better on the 400RV, but I don't expect to ever need to run this more than 5 minutes at a time.
300P and 400P and 400P-RV all have the same duty cycle - 33 percent. The 450P has a 100 percent duty cycle.
