Looks like a joke to me!
A lot of money and too slow to be profitable.
I used to own a 21' Boom Truck delivering concrete block and building material.
Then drove a KW with a 48' Landoll PU and deliver 20-40' containers for a rental company.
Landoll had hydraulic tilt deck and tandem moved 15' with hydraulics.
Way more flexible.
I would have to disagree. I had two run in sheds delivered over a year ago. It did take two trips as one was 32 feet long and one 20 feet plus the 32 footer was on a sales lot and the 20 footer came directly from the builder whom is close by. The sheds were positioned end to end and within a quarter inch of each other with nary a scratch. Also, keep in mind I am discussing a shed which has a certain amount of flex but can be damaged and hot a rigid steel box.
The hauler's trailer was a GN. It had the wheels to go sideways if need be, the deck would raise, the axles/subframe could be adjusted, the bed would stretch both width wise and length wise. The on board gas engine could be started with a handheld remote as well as the trailer adjustments. The tow vehicle was a Dodge dually with a flatbed that also carried the "mule".
I have no idea the price of a Landoll vs a shed trailer or even what a KW is going for these days but a Ram 4x4 is ~50-60k give or take if not more. Then there are your operating costs.
There is an outfit using a road tractor to haul sheds which I see on occasion. I run into the driver whom delivered my buildings on occasion. I asked him about this very subject. He said that one of that company's escort vehicles is a 4x4 Ram which they use at the delivery site to spot the sheds.
Lastly, I delivered pole barn materials for about two years with a 38 foot long Mack tandem dumping flatbed with a knuckle boom crane as well as a single axle Pete with a truss trailer. The company had ten to fourteen crews on so I was kept pretty busy. The reason for the single axle rather than a tandem tractor was to get into tight job sites which were the rule not the exception often as not under less than desirable soil conditions. So, yes, I have been on more than a few delivery's on that job and more.
Landoll's are great but not for every situation.
