Its all about work smart, not hard...get a bunch of blocks...I like 2x4 cutoffs, get some nice long "levers" be it pipe, 2x4's, or I like to use a spud bar. Get (2) 2-3' long pieces of 1" pipe (metal or sch 80 PVC) to use as rollers.
You can work the HC off the side of pallet until it can be rocked up onto one side (I can do this by myself) while someone else pulls the pallet out, then puts a piece of pipe under it to act as a roller...as you roll it, you can "leapfrog" the 2 pipes under the furnace as you roll it along. If you had to move it further I'd say maybe the blower should come off, but I wouldn't bother for 4'.
Or since you only need to move it 4', it might be easier to get a few pieces of sheet metal (like duct metal) to put under the "feet"...it will slide pretty easily on concrete this way (scoot it one end at a time, 1, then the other, in a twisting motion) this is how I moved my Kuuma from its temporary install spot, to its permanent spot...by myself.
I doubt the HC is much heavier than the Tundra was, and I found the Tundra fairly easy to move around...as long as there wasn't lifting (stairs!) involved...same floor/level moves were really pretty easy...heck I did one of my installs, by myself, while the kids were napping in rooms right above me...and nobody woke up!
This is great. How are you using the 2x4 cutoffs (what for)?
I borrowed an engine hoist as well only to find out the legs aren't wide enough .I cheated on mine, borrowed an engine hoist. I put mine up on concrete blocks while I had it in the air, 8" less I have to bend over to load it.
