Well, I'll try and show you the real thing. The first one is an early Pete and if memory serves me ccorrectly it was for sale in Reno at the ATHS Show in 2002 for a decent price. This picture I found on LCM of it being towed backwards.

Gordon Fast Freight, now Gordon trucking built 2 of these up in the 70's. Number 76 and number 80. I think this is 80.
They used 350 Cummins, 13 speed Roadrangers and Pete air leaf rears ,spread. I drove for them then.

Tim has explained pretty much what they are and I was around several that were built and drove a few myself. It was just a way of life in those days. But................. in the 50's when my real KW was built they were knocking out about 6 trucks a week or maybe that was a month and when I retired 15 years ago the plant was knocking out 23 units a day and most likely didn't want to slow production with glider kits.
