Hi
I will give it a try,
Ive got GMC 6500 156" cab to axle set up with a 20k Stellar sliding hooklift which is good for containers 12 feet to 18 feet.
I am a building and remodeling contractor and very happy with set up.
we have a 18' cargo box and three open top containers so far 10, 15 & 20 yards. I am planning to add a 18' flatbed sometime soon.
I use the 10 & 15 for disposal on jobs and the 20 yard as dump truck/ or for loads of loam/stone and moving around bobcat & kaboda backhoe etc.
The truck handles the weight great but have had a couple electrical problems. The turning radius is fantastik better than my pickup.
We will rent out the cans every so often but i dont make a living from it yet, I am hoping to get more & more into it.
I got the 156" CA. because i already had the 18' cargo box from my first truck and it was already setup for my tools & stuff. The box fits the wheelbase great without to much overhang at the rear end.
I got the sliding hooklift version to handle the many different lenght things i wanted carry, It's like the swiss army knife of trucks!
The one thing I dont like about it is the bed of the truck is about a foot higher off the ground than without the hooklift but it is handy to drop it on the ground for some things too. I
Hope this helps you
Mike
