tongue jack blocks for levelling trailer

[ragged_claws]

My wife and I just bought a 16' travel trailer (ECON 16RB). We need to store it in our driveway which has a considerable slope. I need to be able to raise the tongue enough to be able to make the trailer level fore and aft. Once level, I can rest it on the stab jacks or a pair of 6 ton jack stands. My problem is that with the tongue jack fully extended (18") I need at least 16" of blocks under the jack. I have 13 1/2" of 2x6 blocks under the jack now, and it's still not quite level. It also appears a little precarious with the 2x6 block set up and I'm reluctant to stack even more 2x blocks under the jack. Valterra sells a 10 piece block set that's about 8' high. If I were to go this route I would have to stack 20 of their blocks to achieve level. Anyone have any ideas about the advisability of doing this or any alternative ideas?

Thanks,
Kim

Heres my idea. 2 8 X 8 blocks 12 in long. Put a piece of old rubber belt off a mower for a trap and use 2 of them. Make sure you put woodworkers wax on the end after you saw them to length. It will seal it while it drys and keep it from splitting.

and one piece of the 2x6 on top of the blocks to spread the load over the complete block. You should be fine and yes definitely use the wheel chocks!!

Any tree trimmers in your area? A piece of tree works very well for stability and can be rolled out of the way when not in use. Lacking that, I would buy some 6 x 6 and make cribbing to reach your height. I've supported thousands of pounds with both methods.

If you are going to raise it that high make sure you are using wheel chocks on all the wheels...wheel chocks are cheap.

What about making a "concrete" bucket. Get a square 5 gallon bucket and fill it with cement. we make anchors for our boats this way - old kitty little buckets. Attach 2-400 lbs of chain and then a 25 boat swinging in the waves. We haven't lost one yet. The buckets are 24 inches tall at a minimum.

Just a thought!

I've read that cinder blocks can crumble under load. That would be a great option otherwise.
