We had a full on 6 berth Camper van, proper beast, stand up shower, Oven Fridge Freezer lounge area and in the wet with two kids it was too small!! So I think and smaller vans for more than two nights would be rough! We sold it Trafford our house and We wish we still had it!
For us Two kids massive Dog, we worked out that a Van plus quick up tents and Awning shelter was the way to go, tent up in less than ten min, also be awning the same still have a Kombi van for use on Hols so cart bikes, dog, kids about no worries this is good for long weekends away. We do have a full on tent for a week any but that a half hour up and down Job! Plus I’m not carting about all the camper extras
I do use it as my daily driver, and it’s great, but in the end it’s a van! I went SWB as well it was a good deal at times the Len would be helpful but either are easy enough to to park you’ll get you head around them the more you drive them. Yeah it’s noisier than a car, won’t accelerate as quick but that’s a given the seats in our are really comfortable, we did Southampton to Fort Bill in two stops and I felt better getting out than I would have in the previous cars I’ve owned.
