Frank-
That pic of your engine on the 2-wheeled dolly reminded me of a story about "helping a friend".
Phone rings late one Friday night. It's a good friend. "Hey, can you help me move a fridge tomorrow morning? It shouldn't be too tough, you've got that nifty furniture dolly thingie."
Unknowingly, without asking for any further information I say, "Sure" and promptly show up at 8am the next morning with a furniture dolly in the back of my truck. When I show up at his front door, my friend says, "Oh, wheel that thing around back, I'll open the basement door." Now, I'm expecting a walkout basement door, but as I walk around the house I see a set up like yours and instantly I know we're in trouble.
Instantly the door flipped open and he goes, "Come on in!" "Clunk, clunk, clunk" I went down the stairs. The next thing I know I'm standing in a really dark, musty basement next to General Electric's Queen Mary. This thing was HUGE. It was actually a fridge on one side, and a freezer on the other side as if you bolted a fridge and stand up freezer together side by side into one unit. "Well, we're going to need my truck to pull this up." I say. He balks saying his wife doesn't want tire tracks on the lawn. So as we're hooking it up on the dolly, I say, "I'm going to get another strap from my truck, I'll be right back", and quickly disappear back up the steps.
Then I hop in the truck, drive it up on the lawn, hook a tow strap to the front bumper and walk back downstairs with the other end in my hand.
He just laughs and says, "Well, you didn't lie, you went to get another strap! Yeah, I didn't think we would get this thing up the stairs by hand anyway."
5-minutes later, "Thunk, thunk, thunk" up the steps we went... (and the lawn didn't have a mark on it from the 4X4 LOW-Range)
