I am not sure what size a 7.5 gallon tank is, we have 20 or 30 pound tanks on our rv's and that is how we buy. Depending on so many things including temps, wind, insulation etc etc I would go with the same 2-7 days. Until you run it and check it you will not know. Are you in the trailer? If not lower the heat some.
