Most of you have it pretty good from what I see in the pics and have straight stairs or tons of clearance. My stairs are horrible and you can't use a dolly and everything has to be done by hand. These pics are from November 2010 when I got my very first pin High Speed and as you can see the dolly is pretty much useless. You have to lift the pin down to that first landing and then shift it over to the right for the last stretch of stairs to go straight down. That corner is pretty nasty because it has these pie shaped steps so the game doesn't sit level and you have to rock the game side to side to straighten it. You can see in the second pic how tight things are and you can barely squeeze a pinky finger on both sides.
The person I bought my Roadshow from double folded the cardboard between the head and body so the game wouldn't clear at the bottom. Luckily we were able to set the game down and brother in-law was able to grab some tools to remove the slide latch on my cold room door.
Same thing happened when I bought my last game which was WH20 from a friend who wrapped it before dropping it off. The cardboard he used was so thick that on that last stretch down the walls were holding the game up itself. I should have taken a pic but I was more concerned with what to do next but we ended up just pushing it through and that is why I mummify all my games with shrink wrap. When I move games up I remove the head, pull the playfield out of the cabinet and move everything up in 3 trips.
Anyways, after moving around 35+ pins up and down over the years it me under 5 mins from the time we unload from the truck and down into my gameroom. He's been a big help and as you can see from this old collage I made of my first year in the hobby he is all smiles
