Trailer swing clearance

Are you talking about the upper deck?

Most upper decks will come with either 10' or 11' upper decks. The 10' upper deck should have an 18" king pin set back. The 11' can be safe with 30" or 18".

The problem usually is with clearance beyween the landing gear and the rear of the truck. There are some steps with 8' upper decks and even 10' upper decks with a 30" king pin set back. This puts the landing gear very close to the mudflaps and tires of the truck... particularly when taking turns.

Most try to compansate by sliding the 5th wheel all the way back. But many still have problems.

I have a 53' step. 10' upper with 43' on my lower deck. 18" king pin set back, plus my 5th wheel is set all the way back. This gives me plenty of clearance between the landing gear and back of my tractor.

The down side to this is in the overall length of the truck and trailer. Manuvering in tight shallow streets or other places can be challenging. Plus there are roads in many states that limit the over all length and this comination would not be legal. It also adds to the distance between the king pin and center rear axles. When the axles are spread.. my setup is not California legal... Ct and Fl will both fine you.as well. Fl offers a $20 annual permit. Ct if memory serves right will not hassle you as long as you stay on interstate hwys. Cali.. well.. I'm not legal in Cali so I dont run there very much.

I don't know what the swing clearance was but I used to pull a Landoll a fair amount at a previous job and we had to slide our fifth wheels all of he way back and still had to pay attention to the fenders. I know one of our local construction companies runs half fenders on their Landoll tractors. I'm sure you can spec them different ways.

 

I've never bought my own truck and trailer but wouldn't they let you bring your tractor out and test it on a couple different trailers?

 

Probably talking different trailers here (mine's DD/RGN), but I wish I had a flip neck on mine & keep it at 48' unless I need it. It's a struggle getting weight on the steer with some loads. I've got removable mudflaps now which will help get some more weight forward- 5" behind front drive now with 86" swing.

I'm still looking for that 48' 55t trailer with 82-120" adjustable swing, 3 axle, 29' well, hydraulic, that weighs 15,460#.......
