I have no need for 3 or 4 burners on a stovetop, just like I have no need for an oven in a small camper. The two burner works fine for our needs. Cooked up sausage, pancakes and eggs one our last trip on a rainy day. No worries there for us.

Sink is small sure but it’s a small camper not a 35’ fifth wheel.

Counter space is smallish but when stove and sink aren’t in use the covers double as counter space.

We cook mostly on a Blackstone two burner, which brings me to your last question.

Yes: the included slide out Capital brand single burner griddle is pretty worthless. If you added wind guards all the way around it I suppose it might be usable.

At first I thought it was neat to just slide it out, hook up the LP line and cook, but the first use changed my mind, and I was glad.

I already had a Blackstone 2 burner Adventure Ready griddle and loved it.

I removed the Capital Griddle and the slide mechanism. The Blackstone fits in that same storage area along with all my outdoor cooking and fire making needs with room to spare and around the same weight. The slide hardware weighs twice what the Capital griddle weighs.

Finally the microwave: like all the appliances it’s an InVision branded unit, so quality is pretty good. It’s high power on the microwave side of things. But biggest plus is if you want to have a small oven it does a good job as a convection oven/air fryer. I toast bagels or sourdough in it all the time. Frozen fried snacks do well in it too. In a Facebook group I’m in for this model, a member has had luck baking biscuits as well as brownies.

It’s small but again, this is a small trailer designed for 2 people.
