In July of 08 we purchased a new 2009 Big Horn. We volenteer at State Park which is only 15mi. from the dealer, and is a straight shot by county roads to the campground. We live only 3 miles as the crow flys (10mi by road) form our campsite.) so we haven't pulled it over 50 mph since we have had it. I had to take it in to have some work done on it, so I took a round about way to get there. When we hit the hiway and got up to speed (65 in a 70) The Big Horn pulled like a dream. My truck seemed to really enjoy pulling it, just put in in tow/haul set cruise control to 65 and enjoyed the ride. It was maybe 30 miles but can't wait to get it back. I needed to replaced the shocks on the truck, so rears are done and front will/should be done in morning, so it should help the ride even better. Now I wish I had time to really get it out on the road. I may need to take a longer way home when I get it back.
