Canning Outdoors. ( My Eureka Moment)

[Sniper-T]

I have one similar to this:

Cabela's: King Kooker Turkey Fryer

crossed with this:

Wholesale Sports

It's probably 20+ years old, so it doesn't really have a current counterpart any more.

It has no flame adjustments on the unit itself, it is always on, as soon as you turn the bottle on; but I can regulate the flame down as low as I want simply by turning the bottle down low

ETA:
An accepted rule of thumb for cooking a turkey is 3-4 minutes per pound. so, a 15 pound bird takes less than an hour. Doing multiple batches of corn on the cob (water, not oil) I ran mine on full high for almost 6 hours on a single 20# propane tank. When cooking a bird (or anything with oil) you want to watch your temps carefully, as it can creep up to a flash point. So generally, on high, get it up to temp, reduce heat, stabilize temp, add bird, slightly increase heat to regain temp, and then watch, once it starts creeping up again, reduce heat.

sound complicated? it's not! the initial temp stabilization is less than a minute, add the bird, watch it for a minute, then just kinda watch it for the next 1/2 hour, and adjust as necessary.
