I seen some on CL Spokane. it was 7.50$ square foot. regular price they said is 12.50$. way too pricey. Personally, being more of a welder/fabricator, I prefer steel because its easy to repair and very strong. 2" tubing at 24"centers skinned with 16 gauge steel on the outside, and 1/8" wood paneling on the inside. weight isn't a issue for me as the m35 is rated at 10k on road. There was one for sale just like I described on CL Kalispell MT. a month ago. he did a nice job and had super singles on it too. Im sure after a while you'll figure out the ratio between what you want/need, and $$$$.
