24" apartment gas range in 5th wheel?

I have not tried a prime rib in the convection oven, but have made many other things. It's hard to believe, but things brown beautifully, get crisp (the things that are supposed to) and I love it. I had to use the manual for a week or so until I got used to the setting I would use, but I do not miss my regular gas oven at all. Now when I did do a prime rib with the regular oven I had a recipe where you preheated the oven to a real high temp, put the meat in about 15 minutes, turned the oven off and left it in the oven for an hour or so while oven cooled. It turned out wonderful, and I'm sure I could do that with the convection also. Personal choice though.
