Luckydog, we have a 25-foot 2009 Hi-Lo Classic with a wide body. The factory in Ohio put the awning on our Hi-Lo before delivering it to us and, of course, that increased the width of the unit. As Sam said, we also have never had a problem towing the wide body Hi-Lo, except one time when we were a little nervous. We were on I-40 going and returning from a Hi-Lo Rally in Tennessee. Heading to and from Asheville, NC, there are a few narrow tunnels (which were built maybe back in the 1950s) with walls very close to the top edge of the Hi-Lo if you stay strictly in your lane. What we did was slightly ride the center lane with lights on and beep the horn once in a while to oncoming traffic. That convinced me that we would never take the Hi-Lo on the Blue Ridge Parkway because of all of the narrow tunnels built back in the 1940s. The extra width is great though when you are camped, especially with the tip out. What we've done is camp off the Parkway, unhook from the truck, and take the truck on the Parkway. Maybe what the company had in mind when making the Towlite and the 2010 "H" Model less wide was to make these campers more accessible to narrow roadways and historical areas and, at the same time, reduce the weight of the unit. Some states have denied access to wide body RVs in historical areas and their roads.
