I only use mine if the site isn't level and the front of the RV is lower then the rear. This allows the front jack to still have a small stroke and (in my mind) keep the RV a bit more stable.I used to use blocks religiously on my prior camper. It had a 4 point electric, auto leveling system.
However on my 2022 390MP I don't use blocks. The trailer initiates the leveling sequence by lowering the nose /front of the trailer.
I feel the blocks will artificially keep the front from lowering as much as possible. By not allowing the front to go all the way down the trailer ultimately levels itself at a point higher then required.
Maybe I'm wrong but I feel using blocks with my 6 point leveling system is counter productive and defeats the purpose of auto leveling.
I would agree with Jim, I feel the main benefit is to use them when sites are unlevel. They might be needed to ensure you can lift off your hitch in gooseball applications.(fithwheels as well with bad grades)I only use mine if the site isn't level and the front of the RV is lower then the rear.

Full body paint😮fancyI'm not sure but I don't think those orange 'lego' blocks can hold the weight. The red buckets are pretty expensive for what you get (IMHO of course).
I made my own block from 2x6's, that are glued together with a nylon handle. Works for us.

Thanks, that made a lot of sense to me. I learned Something.I would agree with Jim, I feel the main benefit is to use them when sites are unlevel. They might be needed to ensure you can lift off your hitch in gooseball applications.(fithwheels as well with bad grades)
One of the main purposes as you likely know would be to “make up the difference in grade” while still having the range of your jack cylinder available to you for adjustment.
The shorter you keep your jacks results in more stability.
Use or not, it really come down to a game day and personal decision.
As far as affecting the leveling system, level is level regardless of the foundation it is based on, so as long as the nose has the ability to retract to reach level after unhooking, it shouldn’t impact the leveling system.
Thanks Joe! Also thanks for moving my post, I got a lot more comments and insights. It’s always challenging to me to know where to post?In my experience, I generally use nothing. In times where I have a low corner or side, I might use some of my old Hoss Pads. They're 1" thick, 12" square rubber pads.
In my earliest days of camping, I'd use the stackable yellow plastic blocks. These come in orange now too. NOT a fan. They jam up with rock and dirt easily and they can break under the weight of a heavy RV. I broke a lot of them. I don't own any now. Same for wheel chocks. I find the yellow plastic ones to be near useless. Love the big heavy rubber ones though.
