We tow our 27' Kodiak camper (4800LBS dry weight, never weighed it loaded) with our 2008 LR3. We've pulled it out to California, Idaho and all around Colorado. Taking I-15 out to California we had cruise control set at 70-75MPH most of the way. The only time we've really struggled is on mountain passes, 8+% grades and 8K feet plus in altitude. It got over but I was staring at the temp gauge the whole time! I should say the gauge never moved though.
The other thing is gas mileage. I can regularly pull 18-19MPG under normal condition but once I hook up the camper I get 9-10MPG!
