Rick, I tend to agree with the other posts. About 250-300 miles a day is plenty. Now that being said, i've done 650 miles in a day pulling the 5er before due to time constraints. I do not recommend doing that. Every person has a different level of ability, skill, and alertness. Also, evaluate how much you trust your equipment to hold up on the road (tow vehicle & trailer). What type of roads are you traveling, smooth interstate or rough state highways? ---As a rule of thumb, 6 hours a day traveling will allow you to get to your destination and still have time to set up & explore the campground during daylight hours.
