I'm levelling a used trailer house that I bought for storage. I know how to put the blocks under it, which means using solid 4x8x16 blocks against the soil, and stacking concrete blocks under the steel frame. The 4 corners are double stacked, the center ones are single. What I am not sure about is the spacing. What is the recommended spacing between block piles going the length of the trailer? This is a smaller trailer, about 45ft long and 12 wide. I only bought it for storage on my farm. Yes, I do plan to install screw in anchors. Dont worry about building codes, they dont check on storage buildings around here. I just want to be sure there are enough block piles to support it properly.
Thanks
