You're welcome.
mdfiregal and I have built some pretty interesting contraptions to handle several wierd leveling situations. What we have found with the dual axles is that we layout how ever many blocks we need usually 1 or 2 high, back the trailer on, then you can usually remove two or three of the blocks from between the tires to use where ever else they might be needed, something you can't do with 2x10"s.
We started out with one bag of 10 and found them so handy we got another, then another, then another....
We usually use at least three sets when we set up. If the site is fairly level and with the height of our trailer, we found our stabilizer jacks are most stable with about 5 blocks and a cap block under them. Throw another five or six for a single layer under the tires and you can see why four sets!!!
We also have a set of the Lynx chocks (they hook into the blocks) that are real handy to keep from runnning off the blocks when backing on.
