well you don`t mess around  how many working on the project?

This one is the 73rd stretch I've done and my last I hope. There are three in the shop but this job is mainly mine. I always have a plan and I work the plan. I turn down 

3 to 4 of these frame jobs a year. Fifteen years ago the Freightliner dealer I Hermiston, Or. brought me seven day cab tractors to stretch all were the same.  I turned one 

out every 3 1/2 days. I ordered all the rails, inserts and flange bolts before hand. I only have 4 hours in it today.

For a tow truck a long wheelbase gives a longer lever arm so the weight of the front of the truck can more effectively counteract the weight of the towed load behind the rear axle. But a 300" wheelbase is mostly a fashion statement...

Why do people in America stretch the chassis out real long ???
Not been a smart ass but just wondering

That's a good question in some cases. This truck will have a permanent mounted wheel lift for towing. With wheel lifts you need a long wheel base for leverage or

weight on your steer axle .

Yes it's mainly a fashion statement but a 300" WB tow truck with wheel lift is the standard and even longer in some cases. Cement mixers and garbage trucks will tax 

300" tow rig.

paul        same basic  reason you would add counterweight to the rear of a farm tractor      to keep the rear wheels on the ground when using the front loader

but isnt the king pin on the grease plate far enough forward to put weight on steer 

Had a fella here the other day in KW loaded hay for out west and he had a long chassis and asked him why and he said it rides a lot smoother as most of his work is off road pulling road trains 
Not very long by US standards and even with this length it suits only up to 40 foot trailers when he runs as a single

                                  Ran into a snag the outside rails were wrong. They didn't get the sheet square in the press brake and the lips came out tapered. Sent those back,new ones on the way.
