What is the Maximum Distance Required Between the Truck Bed and 5th Wheel Trailer When Towing


what is the max distance from the 5th wheel to the back of the flat bed truck coner

Expert Reply:

The recommended clearance from the rear corner of your truck bed to your fifth wheel trailer when in a turn is 4 inches. If you have a 9ft or 10ft long flat bed, then you may not have the full 4 inches that is recommended.

If you already have a fifth wheel hitch or gooseneck hitch installed on your truck, then you will want to measure from the center of the fifth wheel hitch jaw or the center of the hitch ball in the gooseneck hitch to the rear corner of your truck bed.

Next, measure from the same location to the closes part of the fifth wheel trailer to the truck bed. You will want to subtract the first measurement from the second measurement to determine how much clearance you will have. If you do not have enough clearance, then you may want to look into either using a sliding fifth wheel hitch which will extend the pivot point 10 to 12 inches rearward or a sidewinder pin box which will extend the pivot point 22 inches rearward.

If you can send me the year, make and model of your truck as well as the length and width of your truck bed, then I can let you know what will be needed to safely tow your fifth wheel trailer without hitting your truck bed.
