Plan for the van

I've been looking at some great van conversion videos on YouTube and can't wait until we find our perfect van.  It'll be our only vehicle and we hope to get many years out of it so we want to be certain that we choose the right size. Nothing too big as we want to keep the running costs down and fuel is ridiculously expensive so the more economical the better.  I'm really excited at the prospect of stripping it all back and creating our tent on wheels.  I don't want a proper van conversion but simply a bed frame with plenty of storage underneath.  We'll only be using it in decent weather and  cooking simple one pan meals al fresco. I can't wait.
