221"wheelbase

Well how big is the sleeper? I have a 48" sleeper and a 215" wheel base. It's just big enough for a 48' flat.

 

Typically the shorter the wheelbase the rougher the ride. Makes getting around easier with a shorter wheelbase. I have a 232" WB with a 77" sleeper.

All depends on what your operation is. Guys I load up and run with have 300" WB trucks. They move around just as easily from what I see. Then again I watch guys with a Cascadia struggle to hit the dock.

 

I ran some Prostars with 220" WB and 56" sleeper. The only time I had a problem was on some pipe loads if there was more than 10' forward of the kingpin. I also had a headache rack behind the sleeper that was set back to clear the back-of-sleeper exhaust too.

Dry van, reefer, or any normal deck loads shouldn't be a problem.

 

Look.at how far the front axle is setback. Also kingpin distance on the flat trailer vs a van.

 

Then drag out your grade-school math and calculate the hypotenuse of the right triangle formed with the half-width of the trailer and the kingpin. This will tell you how far it is from the kingpin (centre of the fifth wheel) to the corner of the trailer so you know how far forward the corner of the trailer will project when making a turn.

(A x A) + (B x B) = C x C

Assume 102" wide trailer and 30" kingpin setback.

A = half-width of the trailer (distance from edge of trailer to centre of kingpin)
B = kingpin setback
C = distance from kingpin to trailer corner
​

(51*51) + (30*30) = 3501
square root of 3501 is 59.17... so, call it 60"
​

Or, you can Google "hypotenuse calculator" and use that.
