Ditto the Peak series, my quest for a Peak brought me to a Coleman "Exponent" which seems to be a newer version of the same thing, came with two generators, one for diesel the other for gas and naptha/"camping fuel". Did not however come with the same nifty case I have seen with the Peak stoves.
Have both Coleman Peak 1 and also an older Coleman (bigger tank) that is also petrol compatible.
Both have been rock solid and the most I've had to do is re-vitalize the cup on the pump (though I do carry a spare generator and pump assy). Had them for 20+ years and they go on all camping trips. Decent simmer capability too. Flat out they push some serious heat.
Though, I do prefer to use the coleman white gas or equivalent just because it evaporates quickly with minimal lingering smell. I take a small bottle of extra fuel on longer trips and eventually resort to petrol when needed.
Ditto. I have 3 iterations of the coleman multifuel single burners, and all are rock solid performers with minimal issues. Peak 1, Exponent and the lastest version I bought last spring. I traveled in Mexico for 2 years in my '99 Tacoma where white gas wasnt readily available and had to use gasoline. Had some generator issues so now I have a back up to my back up, just in case. Seems like overkill, but I gotta have my cafe con leche.
While Colemans' work well and are reliable, a step up in reliability is the MSR range of expedition stoves. They are very light, and are very easy to service in the field. They'll also burn kerosene which the Colemans' dont' run well on. I have had an MSR Whisperlite since the early 80s which has worked flawlessly since then with only minor maintenance: jet cleaning, new gaskets.
,I have a small backpacking single burner gas stove I carry in my aircraft survival bag. Have used it over the 40 years without issue. Also have the Coleman single burner gas stove and use it a lot, again without issues. Good luck in you decision.
