With the Goose Box installed, you will likely still have trouble making tight turns with your short bed truck, but there is a formula that can help you confirm this. Reese Goose Boxwill not provide any additional clearance for short bed trucks above what the factory pin box offers. The existing pin box on your trailer should have a sticker or plate on it that lists its model. This unit is designed to replace the Lippert 1621, 1621HD, and 0719 pin boxes. The Reese Goose Boxes are designed to replace specific pin box models on the short bed trailer so you will want to first make sure that it will be compatible. If you have been towing a 5th wheel trailer with your existing short bed truck and a sliding hitch was needed to execute sharp turns then the Reese Goose Box 20K won’t be a good option. Turning clearance may indeed be an issue with the Reese goose box short bed as it does not provide any type of offset and you won’t be able to rely on sliding travel from a sliding 5th wheel hitch. It can’t quite get a full 90 degrees out of this set up without dinging the cab, but you will get plenty close enough for what you need. There is plenty of room for the Goose Box to turn in the bed without rubbing on the 24″ wide for reference tool box. So you can see, a Ford and Ram require a trailer that has more fore and aft distance between the contact point of the trailer and the king pin, whereas GM and Toyota require none.Reese Goose Box will works great on a short bed trucks with an auxiliary tool box mounted in the bed. The two drawings below show how to find the contact point and how to measure the distance between it and the king pin:įind your truck manufacturer (current body style) on the chart below to find the required distance ahead of the contact point: The greater the distance between the cab's contact point and the king pin, the better that trailer is suited for this truck application. Anything above the cab line is of no consequence (see figure 3 below). The corners of a trailer, like the one in Figure 2, is going to contact the cab much quicker than one without their corners removed and contoured (Figure 1), however, the nose cap of your trailer is only of concern below the cab line. The trailer nose cap may overhang the king pin in the middle like the Cougar trailer below on the left, but at the corners, they're behind the king pin. Many trailers today have contoured nose caps like those shown below. For example, your trailer must not be more than 96” wide, and the distance your king pin box extends forward of your trailer nose cap, may be critical depending on the truck model you purchase. Now, not every trailer is going to be a candidate for these types of truck models, even when using the #3100 or #3200 SuperGlide. The #3100 and #3200 SuperGlides are the ONLY hitch of any type or brand that travels 22-3/4".exactly what you need for this type of truck! Take a look at the next animation to see the model 3100 in action. There are no other SuperGlide hitches that travel more than 18". There are no manual sliding hitches made that travel more than 12". So, the real distance you need to travel is 19-3/4" + 3", or 22-3/4". You need more clearance to account for road contours.let's say 3". If you think about it, 19-3/4" is not enough clearance. But your 5-1/2' bed truck does not provide sufficient cab clearance by a whopping 19-3/4"! Not ideal, but manageable provided you watch your tighter turns, and purchase or use a slider type hitch, manual or automatic. A 6' bed truck does not allow for a full 90 degree turn and does not provide sufficient cab clearance by 8". "(cab to axle) - (half of trailer width) = cab clearance" is the formula used in the chart below:Ģ8.25” - 48” = -19.75 negative cab clearanceĪs you can see, an 8' bed truck provides more clearance than needed. In order to help you understand the challenge of this body style, let's compare the trailer to cab clearance for an 8', 6' and 5-1/2' bed for a Ford truck. So if you're going to use this style of truck, let’s do the math to see how much clearance you really need to keep your trailer from hitting the cab.
