I would like to see how you made it level, Did you use Deck screws and or use Deck nails and which size did you use.

To all:

If you have a "Solar City" in your area they give away the best pallets. I had a Solar System put on my house and they (The Crew) gave me all the pallets I wanted when I asked for them. They are near mint quality 5x7 pine pallets. They have to take them with them when they leave unless someone asks for them and they are always happy to give them away. They (The Crew) said if I wanted more to just go to their yards and ask for them and they will even load them for you. They are happy to do this because they have to get rid of them. at least this is what the crew told me who put the system on my house. I have not gone to get more yet cause I am still going through the ones they gave me and now after seeing this project I think I will try and give them a call for a few more to try this build.
