We have a cab-over camper, Lance, and tow a large enclosed with our toys and we were concerned we were putting too much stress on the hitch extension, truck, or both. This tool out our minds at ease and helped us figure out tongue weight, overall weight, and bed weight. The only complaint I have is the camper exceeds the max scale for payload and so a reading for payload with the camper doesn't help us out, though it would if the camper was less than 3500 lbs. We will be buying one of these for each family member who tows trailers, its so dang handy..
