I cannot imagine bringing a 110 volt compressor for RV use. I rarely camp with hook ups and I would want to be able to deal with a tire out on the road.
Ten years ago I bought a cheapie, Slime compressor from Walmart. It was about $35 and the equivalent units are not much more expensive now. I have used it a great many times. It is slow if you need to pump up a tire that has leaked. I use it mainly for adjusting tire pressure over time or due to temperature changes. In addition to being cheap it takes up very little space.
