Maybe Andy can strap his BBQ to the back of the transporter... dunno
Mine's broken as I threw away the grille at the bottom by accident when getting rid of spent charcoal, doh! Besides, we can't fit it in the Hatchi, with parts, tools, etc + Daniel and I inside for the trip to Nikko unfortunately. I put a cheap BBQ in the bushes last year, it might still be there...? It's only tiny though.
Your awning might be nice, but you can't cook under it..
We usually rig up a couple of hammocks under the pit roof, assuming we get there early enough.... but people are usually afraid to lie on 'em cos they look flimsy (...they're not!
