Unfortunately I don’t have pictures and I no longer need to unload on a slopped driveway but I once did. I found that lifting the camper off the slopped truck bed was challenging, especially when reloading and it placed a lot of stress on the jacks. I would back part way, get out and slide ramps under my front tires and then using 4x4 low range back up the ramps. I made a set of 10” tall wheel ramps from pressure treated lumber that allowed me to back up the driveway and be level. I made four blocks from the same lumber that compensated for the slope so my jack bottoms were level and could not “walk” down my driveway. Using the side of my driveway as a guide and placing small paint marks to show where the ramps should be placed the loading and unloading process was relatively easy.
PS, I’ve had the same 30 orange Lego blocks i use for leveling the truck and placing under the jacks for over eight years with no breakage. Lumber is fine but heavy!
Lego levelers, no problem under the jacks, if you only use one and don't stack them. I was referring to what the OP may have purchased, based on what he said, albeit sort of vague.
Regarding unloading on a steeper hardscaped slope, yes, having a tapered base plate under each jack is advisable/necessary. But the rest of the process you describe sounds wholly unnecessary, especially if 10" tall ramps leveled up the truck, your driveway was at about a 3.5 deg or 7% slope. Wort case you'd run out of jack travel on the front jacks and maybe need to block those up compared to the rear.
Regarding loading and unloading, especially in a known set of conditions, it's just too easy to figure out where the jacks need to be to get out from under the camper the first time and then just run the jacks back to the same position each time.
I'd do that all the time if we were camping and unloaded on very uneven ground. Get the camper up to where the truck will pull out. Mark the jacks and then just run them back up to those marks when loading back up. It did take all the fun and suspense out of it though...lol.
