from experience, do not get the little buddy. it won’t be enough in a large thermal, tried it in a friends. he’s going to buy a sunflower. a sunflower puts out way more heat, more than the big buddy.
That being said, i run a big buddy that is almost not enough on cold windy days so i’m trying out a new mod i made to my big buddy.
i retro fitted and eliminated the need for d cell batteries by wiring in two six volt mojo batteries, will jumper them to use my 12 volt vex charger when needed. the batteries fit in one side of the propane cylinder compartment since they never get used.
i don’t have any experience fishing in such a large potable as yours but with the fan i think you’ll happier with the big buddy. going on 10 plus years with my big buddy heater/same flip over and am just getting around to using the fan.
i had clam 8×8 sleeper back in the day and it required a double sunflower to stay warm below 10 degrees and wind, it was not a thermal.
