I have a 211 on the way.

Now I have to figure out what size gas bottles to get. Maybe get the large rental to keep in the shop.

The largest purchase size is the 160 at my LWS.

The 160 is still kind of heavy so thinking for my truck I'll get the 80. Should get close to 4 hours out of it and I need to save space and weight.

There has got to be a way to refill the small tank from the large (225 I think) tank. I saw a post about it somewhere online but lost it. I would like to have that option with such a small tank or I may need to rethink for a 160 portable.
