Congrats, Wayne, on the new tank!
Hope it goes well for ya!
Watch that sharp corner, I've had friends who took out the corner and the adjacent wall to fit tank through because they were half way down the stairs and cannot go back up (ran out of gas). So they had to do that and it still couldn't fit, didn't want to knock the whole wall down.
Ended up calling more friends to tie/drag it back UP the stairs. Huge repair bills, never mind a few scraped-up friends. Sold the tank to another guy.
Sometimes it's worth have a tank/ stand build on site for that exact reason. Esp if you want to keep all your friends!

Keep us posted. Hope to see you at the meet this Saturday!
Lenny.
