I use TWO sets of TEN leveling blocks. They interlock and TEN are the most I would ever use in the past, but finding a $5 bill blowing in the grass as a super wind fall, we went for 20.
I also like to use a 2" x 10" x 10" blocks, or 12", but a couple of 1" thick one on top and the other at the bottom will work. The 1" thick boards will split sooner than later, so go to Lowes or Home Depot and ask to go through their SCRAP TRASH can. My 12" x 2" thick boards were scrap they cut off a longer board for someone for FREE. Trash is good. If you need to buy a pair... find $5 blowing around the lot at Walmart, go for it.
I gave out last ones with the 25 foot International when we sold it. The 1" thick I had do not cut it... the bottom one will split due to uneven ground. The 2" are the best.
You sandwich the leveling blocks like a peanut butter sandwich.
I slide the stack under the Power Jack BEFORE detaching. The jack only needs to go a short distance to detach and a short distance to be LEVELED. If I can do it... your Dog can do it. Our Heelers watch and supervise.
The Lynx were bought by Nancy on the Internet
www.lynxlevelers.com priced for $39.95. Nancy may have bought them at WalMart. They have a handle that holds the ten blocks as a group and very handy. Maybe $20 for the levelers and $19.95 for liability insurance since people have weird uses outside of trailer, kind of thing. They come in a blue carrying bag. You can use it as a HAT if your head is a CUBE... just getting your attention.
I use them for stacking under the JACK. I use them for Side to Side. You can put one under your leveling jacks. You can keep the trailer attached and level side to side. You can keep the trailer attached, add two or three to lift the front, as well. Any more you are best to detach and get out the CHOCKS to keep the trailer from rolling away into the Forest.
You can get 12 to 16 in the rear storage. Ten for sure with room to spare.
Better yet. Get a stack of 2" thick lumber and get it for FREE. Woodsy color looks chic in the Forest.
They are not slippery. Flimsy. Crush... but can break or crack if on a rock. Come on... I have used them for 14 years and they have been places most of you never want to get close...
I now have orange and yellow ones. Each use a different pattern, so I cannot mix. If you need 20... get the same brand so they fit together. I had the yellow and no idea from where... Nancy bought orange. All work just fine.
Mix and Match on the Side to Side. Just stack the same blocks together.
The boat in Mina, Nevada was level and out of water. Imagine that.
Tent is level. I have tent camped on the side of Mount Antero, Colorado and by morning sliding out the front entry... No kidding. With two dogs. It is over 14,000 feet high. That are a lot of legos... trust me.
Shop around. Get some lumber. Get leveling bubble units for a couple bucks each and attach one for Front to Back level, and the other for Left to Right Level. Mine measure 3.75 inches by 1.25 inches. YOU do not need the giant ones for those who cannot see well. They have some big BALL in it. Get the one with the green or clear liquid with the bubble. It works just fine. The green will turn clear after some years.
Any questions? Any additional comments? Are we happy? Yep... Life sucks when sleeping in a trailer when you find yourself sliding onto the floor by morning because one end is off by 12 inches.
Added: Drive onto one, two and up to the level you want. If more than FOUR... move to some other spot if possible. Take the ones driven over and add as you go. Determine how far you need to go to get level. You do not want to be adding levelers and be in some other part of the camp ground. See the last photo...
To get off, go four to three... ahhhh... I see. You are catching on. Now... go camping and enjoy yourself. I am on the level... trust me.
