Truck/RV levellers?

[Powerstroke2000]

I thought I would see what some of you find most useful when it comes to levelling your truck when you get to a site! I was just on a recent trip, and I usually carry along some 2X10 wood blocks, but forgot them this time around. Trying to buy some along the way produced little results, as no one seemed to be stocking them (perhaps because it's still winter?)
At any rate, looking on Ebay, I see there are several brands/types, and wondered if any of you had found the 'ideal' levellers to run the truck up no to, to level the whole unit?
I'm finding even some of the paved sites in some State Parks are far from level!

Any info on these would be appreciated!

Thanks.

I use a pair of Camco Tri-levelers.

After many years of rving I find that level is a state of mind and I don't worry about it unless I roll out of bed! Park it and enjoy your stay!!

I use the leggo type mainly because they are fun!

I use the Leggo type mainly because they store in smaller spaces. Since you live in cold country be aware they have the potential to crack when cold.
