Good question. The simple answer is that we don’t cook much in the van. The most we do is re-heat something, and maybe cook some pasta. This tends to be if we are on a weekend away.
Longer holidays have tended to be somewhere warmer, when we cook outside, or maybe in the awning. We also eat out a fair bit when away.
Once we are pitched up with the passenger seat swivelled around, we just don’t need to stand up, as everything is to hand.
I don’t think we have ever said “if only we had more headroom”.
