Hi all,
I guess I'll add my 2¢ to the discussion.
I'll be burned alive for heresy because I am suggesting this, but if you absolutely don't want feet on a dutch oven then buy the oven you like and cut them off. Lodge and Camp Chef have produced them by the millions so you won't be ruining any future value. You will be able to cook on a grill or by using a lid stand to hold it over the coals.
I actually think that most folks worry way too much about seasoning their ovens. I heard about a guy who got into a marriage threatening fight because his wife washed his Dutch Oven with soapy water. Really? Over the seasoning in a Dutch Oven? Don't get me wrong, I don't recommend washing them in soapy water but it does not ruin them!
The real seasoning in a Dutch Oven comes from the carbonization of fat on the surface of the oven. Once the the oven has been seasoned it's reasonably difficult to damage it during normal usage. I rarely have to strip an oven and reseason it.
When it comes to seasoning ovens, I believe that the temp you season at is more important than the specific oil you use. I like the high-temp method of seasoning. I try to season between 500°-550°F to achieve a beautiful dark black seasoning. Much hotter than that and you run the risk of burning off the seasoning. If your oven comes out with sticky places, you used too much oil. If it comes out dark brown, you didn't get a high enough temp or didn't let it "bake" long enough.
Lastly, consider using your gas grill rather than smoking up you house. Most grills will get plenty hot enough. You do need to make certain that you have a decent thermometer so you can monitor the temp.
Honestly, the best way to keep you cast iron well seasoned is to use them regularly. I have a Wagner skillet that was my mom's and it had been neglected for years when I got it. After some regular use the seasoning is beautiful and I can fry eggs in it without having to worry about them sticking. I love my cast iron, but I don't get my panties in a knot about the seasoning.
Just my thoughts....
