Yes, they do! For safety, if nothing else. Plus, some models of WDH's have anti-sway capabilities built in, which is good in side winds and passing big rigs. They do not improve gas mileage, but going 65 gets you better gas mileage than going 75! You must follow the truck regs for highway speeds in some states. Also you must have side mirrors that are wider than the trailer. In Colorado a state trooper will pull up behind you and move to the left slightly to see down the side of your trailer. If he doesn't see a mirror, you'll get a ticket. luckily there are Camping World Stores along I-70 and I-25 in Colorado.
