The benefit of running propane is you will not have carb issues. The reason I have not converted our Honda to dual use is the only time we need a genny is winter camping...which is when we also need the most propane (for heat). So I did not want our heat source and fuel source to be the same...I would not be able to carry enough propane! I am careful to run our genny 1/mo all year to be sure the carb is not gumming up. I also add sea-foam to the fuel (as with all of our small gas motors.
The 1 gal tank on the H2K will run 10-12 hrs...which is plenty for a 2-3 day ski trip....so we don't even need to carry spare fuel. Just fill the genny and off we go.
One other comment about size; the 2k genny's are easily portable...have you seen the size of the 2.4k and 3k gennys?
I would not want to carry one...
Make sure you NEED that much juice before you buy one.
