My tank has a bunch of numbers/ info on it hard to read, but does say Gal--23.2
I am not too clear on what that means wrt "full" in litres even after reading a lot of Google articles and the posts in this thread, but I will get it straight eventually. :(
At the moment, I think I have the equivalent of about two and a half 30 lb bottles so that helps predict how long I can go before a refill ASSuming similar consumption as in the 5er. Actually this MH is easier to heat, so should do better.
Also looks like I will not need an extend a stay after all, like I was planning on, maybe later with more experience. Might get the BBQ adapter though.
Anyway, thanks for the help with all this.
