I'm looking at new Toy Haulers. My '12 3500 4x4 sits 58" high at the rear of the bed. I measured the height of a Cyclone today at an RV show - it was 60 inches. It looked to be sitting level. I know I want to be as level as possible when towing to distribute the load evenly between axles. My truck is sitting at the stock height and I have no plans to lift it any. I am new to 5th wheels - what is an acceptable clearance between the trailer and the sides of the bed? How do I achieve this? Install a lift kit on the trailer? Are some trailers made taller than others? I realize the truck will squat slightly when hooked up, I have air bags and plan to keep the truck level. What are your experiences with this stuff? Do I just need to shop for a trailer that is tall enough? It seems to me that this should not be a problem with a stock height truck. Like I said, I'm new to 5th wheels, all the trailer salesmen know is that their trailer is bright and shiny! They have no answers at all. I guess they might be stupid questions on my part, but I need to get my ducks in a row before I drop some big bucks on a new Hauler. Any input would be greatly appreciated. Thanks, Tim
