Well i have this post else where but thought i would post here as well. Its always nice to get input from different sources.
i have been lurking Expo sites for awhile getting ideas for my own, i am building my box structure from wood rather than the seems to be normal steel. I have good faith in the structure to hold up to the rigors of what ill use it for. Wood structure is significantly lighter that's for sure.
the build is underway, and will progress hopefully be done by spring.
