That's funny Sparky because my story is similar. The truck got stuck coming up the lane. I could have pulled it but didn't have a chain and my truck was in front of his and I couldn't pass to go get one. Luckily I had a cooperative driver, he used chains. The problem was more with the truck than the lane. I had 2 crates containing a 1604, 62" laminator, 65" plotter and the stands. The liftgate was insufficient, but the 3 of us got it done.
On carrying it upstairs... width is probably the issue. It's not hard to move with 4 people but up stairs.. I'd hesitate.
