> A MSR-fired hot tub. (Thomas DavidinKenai)
This I gotta see, how did it work?
I've considered making one of these and I think I could make one with enough fuel for 3 hours of operation and have it weigh less than 40lb.
Now, the heaviest thing I've seen was me for an overnight hike with my Uni. Midwinter 4000 foot ascent at night for the purpose of celebration.
My pack weight was around 80lb. I had a cast iron fry pan, an ad hoc oven, 4lb flour, 3lb asparagus, 1.5lb butter, 24 eggs, 4lb of bacon and 1lb of white gas.
The following night we cooked fresh bread rolls, asparagus with sauce hollandaise, cheese fondue and meringues for dessert. With a breakfast of eggs benedict it was pure gluttony.
It took me 4 hours to walk 4 miles with a 4000 feet ascent.
.... and that's why I decided to go UL from then on.
