I know The Flame Pit have just had a new trailer made and it looks awesome (@yeatsy) on twitter. He had it built in the UK and it took about 4 weeks.
We are currently building our own based on Gator pits Texas renegade, although we are putting 2 Santa Maria grills, a sink, a gas ring and a fridge down the one side as opposed to another horizontal smoke chamber. I am not sure there is really the market for these in the UK. I believe Europe as greater potential but the market penetration costs are just too high to consider making a new business from it. On the other hand this fits nicely along side the auto/ aero and defence work we do so can make them as ongoing projects.
I will post some pics when it starts taking shape but for the time bring you can see the horozontal chamber being rolled here
