I have used a dutch oven a lot, and it is a great cooking vessel. However, it is way too heavy for me to want to bring along in our trailer, plus unless you bury it in coals, or at least put them on the lid, it cooks from the bottom up, leaving many foods cooked way more towards the bottom of the pan. At home, it is always the go to pot for cooking in the oven though, where it is fully surrounded by heat.
As shown in the link I provided for those two stovetop stoves, I have used the Outback Oven hordes of times in the past, mostly while on backcountry canoe trips. It is very light and packs small, plus works very good. You do have to be able to produce a controlled small flame to make it work good.

I have been reading a bit on the Omnia and Fox Hill ovens, and it seems the Fox Hill might be the best performer, not too heavy, but a bit on the bulky side.
I really like the idea of the Omnia, and am very tempted to pull the pin on ordering one. Very light (0.5 kg), and not to big. The biggest downfall seems to be storing it, as it is a light aluminum.
Still, the BBQ does work great, but the Omnia could be making some nice bread while the steaks and corn are on the barby.
