For those of you that employ either mud flaps on the truck and/or the fifth wheel can you vouch for their effectiveness and tell us what make/type you use. Paul
They work but you have to get big enough ones to do so. Most of the cheapo toy flaps like the ones that come with trucks, are nearly useless. I did a lot of reearch and the best brand IMHO is Duraflap. They are large, tough and perfeclty fitted. THey will cost more but if you want a flap that isn't just for looks, they are great. They're American made too.
