I have a 2007 Frontier SE 4x4 and want to get a 19 to 24 foot RV trailer. The Frontier's rated towing capacity is 6500 lbs. The weight of these trailers is usually around 3500 lbs. Does anyone have any experience towing a trailer like this with the Frontier? I'm new to the RV world and really don't want to have to get a different truck.
