Wisconsin man creates new towing invention

(Aug. 24, 2015) -- “I’m an RV owner and would use my tow dolly to tow a car behind the RV, but the rest of the year the dolly would sit in my yard unused,” Grape told the Wausau Herald. “Other times I would want to haul lumber or my riding lawn mower and would need to borrow a utility trailer from someone. I wanted to find a way to somehow combine the two.”
