i built one 6 1/2 ft wide by 10 ft long, have had it a couple years. If you can drive a truck on the lake, the wheelhouse will be ok. Mine has a 4" steel square tubing frame with 4" steel I beams across the middle. The back is designed to open to allow for a 4 wheeler, but it is actually a little heavy for a 4 wheeler to move around. To keep it from freezing to the ice you lay down 2 x 4's at the corners and tongue.
