I haven't done it yet, but I am going to very soon. At first I was looking at the Wallas 2000t, which is the more powerful kerosene model. I've read that a lot of people have been happy with the 1300. I called scan marine and talked to Doug about the options, and learned one very important thing. The kerosene models have a return fuel line that needs to go back to the tank, and it cannot have any traps in it. Since I am putting a larger diesel tank in between my fuel tanks, I wasn't sure if I could make this happen. I'm leaning toward the 22GB. The Viking Air looks like a nice unit also. Way more heat than you would probably need, but it still turns down to the same levels and power draw as the 22GB.
