One of the major reasons my wife and I bought our Apex 189FBS was because it had a "full" kitchen with an oven. All the other sub 24' ultralites just had microwaves.
I just use a round teflon pizza sheet pan to difuse the heat. Being able to cook inside when it is a bit frigid outside is well worth it!! I made a full New Years day dinner with turkey breast, stuffing, baked yams, roasted carrots, gravy, fresh cranberry sauce and brussel sprouts in my little compact kitchen. It was 30 degrees outside!
I also setup an outdoor kitchen with a 2 burner stove, small weber grill and a large dutch oven.
