I definately like having the usable counter space with the covers down considering much of the time they aren't in use. Plus we'll put dirty dishes and such in the sink if we're doing them later and still have the work space, etc. I've only gotten in a few over nighters so far but we have a 2 week trip coming up that will get some solid use on them (haven't been out with the faucet on the sink yet so no feedback there). The stove I have has two different sized burners 47mm & 62mm, not sure the BTU's but the 62mm which is on the right (nice because its farthest away from the back of the camper in my setup) seems to have a quart of water at boil in a couple minutes which is good to go in my book. No problems doing eggs, etc. with a 10" cast iron skillet either. The push button ignition is nice as well.
Overall moving the stove were I did made me happy, getting these units makes everything even more usable which makes me happier.
Edit: Also compared to the original stove which was 10years old this seems to have less "fumes" as it burns. Don't know if that is more an issue of the difference of construction or the age.
