I towed a Lunar Ariva 1tonne caravan with a Ioniq 5 Premium from October to January 25. The Premium has a bit better range than the N line. I am not heavy footed when towing and try to anticipate well ahead. We go away most weekends on Rallies in East Yorkshire and Linconshire with only basic facilities and use V2L when possible depending on how far we have towed. We charge at home with at 6.7p with Eon. Our furthest trip with this van was 65miles to Ripon Race Course in late October, we got 2.2miles per kw going and 1.9miles(windy and colder) on our return mostly A roads and M/way, we used 6kw on V2L.
In January 25 we changed to a Elddis Xplore 586 1.4tonne. Our longest tow with this van was to Worksop 52 miles in early February , we got 2miles per kw going and 1.6miles( much colder and a faster speed) on our return mostly A roads and M/Way, we used 12kw on V2L.
We do limit how far we travel and find plenty of meets we can attend. We have run the the van on electric only (heating and cooking) for the two of us on shorter journeys.
On the rare meet when we had hook up we topped up the car with a small amount without any problem.
Hope this helps you to decide. Any questions just ask.
