Cluffsb-I got my camper out of storage today and parked it in my yard. I was thinking I might flush out the anti freeze and sanitize the water system but the forecast is still too cold for this next week. Predictions are for mid-teens for a low Wed night. So I guess I leave the AF in for another week at least.
I measured the oven. It is 16" deep. 15" wide and 16" tall. But you only cook on about the top 10". The lower 6" is the heating element (below the gray shelf in the photo). Also good for storage, pans, bread etc..
As Wisc wrote, many folks are not happy with the oven until a pizza stone is put at the bottom to more evenly disperse the heat. I haven't invested in one yet. I'm not much of a cook, so far I've used the oven for a couple of frozen pizzas. It worked well for that as long as you rotate the pizza.
Hope you enjoy your new TT when it arrives. We do.
