What is the best single burner sunflower heater out there? I have a Otter Cabin to heat. I am going to use a 4.5 pound tank. I have a Sportsman's Caddy in my Otter and I want to leave the tank in the tub, use a hose and then figure out a bracket that I can mount to the Sportsman's Caddy and slide the heater head onto. I now have a Buddy heater but I would like to go with my plan and eliminate the Buddy so I have more floor space. Thanks!
