Yes we do, in our Panel Van, but not the "home" one as thats a bit big.
We take a small one thats just big enough for 2 (the air fryer not PVC !) purchased from Lidl for about £25. It complements the Remoska which also gets used a huge amount at home (that only draws 400 watts so very handy when on 6a supply) .
In addition we take a single induction hob away with us, so our gas consumption is pretty minimal when on site/EHU.
