A friend had a 60 gal unit that died and he replaced it with an 80 gal IR upright unit. Store loaded on to his pickup (with pallet attached). When he got it to his garage, it took 4 (BIG) guys to unload it and put in place. He said that for a while he thought it might have to stay on the pickup forever.

Nearly mandatory to have an 80 gal or larger unit when you do a lot of air work. Thinking of getting a new 60 for myself this year, but I don't do a great deal of air work, and especially very limited painting.
