HEY there!
I just got that very same safe from Sam's Club a month ago.
Here's my recommendation. A handtruck/dolly that is rated for 600-700lbs is fine. They sell those at Sam's also. You can tell which ones they are. They have the inflatable tires. Lighterweight dollys have the solid rubber tires that are much smaller and thinner.
Get 1 good strong extra friend. 2 would be better, but depending on people's size/strength, 2 total people might be fine.
Buy it. When you go to the back of the store to receiving, make sure they lay the safe down on ITS BACK onto your truck. Otherwise, it will crush the combination or bend the handle. (sounds like common sense, but people have actually done that)
Before they load it up for you (if you're not getting delivery) make them take the box off (it comes off easy, is 1 piece) and bring a 9-volt battery. The keypad slides off upwards. Put the battery in. Put the keypad back on. Then put in the combo. It is 1-2-3-4-5-6. Check to see if it opens. Do this AT THE STORE. Worst thing in the world would be to bring a defective safe to your home then have to move it again or deal with a return process. They will give you looks or attitude for wanting to test it there. Tell them you demand to do it. I did, they let me. Put the box back on for loading to avoid scratches.
I left the skid/palette attached to the bottom of the safe. This means I had to leave my tailgate open and the safe only went into the bad until the skid reached the open tailgate. Then I tied it down.
DON'T let those idiots use the fork lift to slide it up in there. It isn't that heavy. 2 guys can slowly tip it onto the tailgate, and once the weight is on there, you grab from the bottom and heave it up on there. It isn't that bad. 2 guys can do it. I spent 20 minutes bitching at the Sam's Club guys trying to convince them not to do it that way, then it took me and 1 buddy a whopping 5 seconds to just lift it in by hand. If they use the forks, they will either scratch it, or drop it. If they drop the safe - DON'T Buy it. Any small drop can warp the safe to make it useless. It can also damage the internal mechanisms.
Once home. Just slide it till the weight is about to make it tip off the bed of the truck, then 2 guys can ease it to the ground with no impact. Then get behind it and tip it upright. Piece of cake.
At this stage, open the safe - remove all the shelving and stuff from inside. This lowers the weight a little. While one person holds the safe, the other should unbolt it from the wooden skid. You will have to remove these small white plastic plugs to get to the bolts. Use a thin flat head screwdriver and be careful so you don't rip the interior. Slide the safe off the skid. Take some of the plastic wrapping that was used to cover the safe, and line your dolly with it before pressing it up against the safe. This ensures it wont scratch it.
Rest is just rolling it in and placing it. It isn't that bad, but I don't know your size/strength. It wasn't that bad for me, and I am 5'11" 195. Buddy is good to help direct you, and to grab it if you start slipping.
This is a good safe. I love mine. Remember to change the combination. It is easy. The process sounds much worse than it really is. You just need to get your ducks in a row prior to moving, and have a plan. If you do not, you will either make it harder, or will incur damage.
Good luck.
