Like a Scale Crawler? I guess you could look into raising the suspention somwhow, Get some beefy wheels. That would be a good start Id think. Dont have any crawlers, scale crawlers nor have I ever built one. So my advice is kinda just guesses and general thought. Maybe some crawler wheels w/beadlocks and setting the suspention up as high as you could get it might get ya around some trails. Maybe some one who builds these would have better ideas. Just Bashin MTs here.
