Let's be honest slowmover, 99% of full size pick ups spend 99% of their time moving nothing more than themselves and a driver.
I've got a 2.5t GCM. I still beat NEDC with a full load. Just on the weekend I had about 800lbs of pavers in the back followed by 15 bags on concrete on Monday.
I also have a big van, but it's so long that I struggle to tow with it. It's around 30' long with a 10' trailer, so I deliberately wanted something small and maneuverable so I could get into narrow inner city driveways. One time I had to park two city blocks away as the van wasn't even close to a fit in the under ground parking.
This was a great combo, can't think of anything more practical. Still miss my little Kangoo: 2.4 tons as pictured (3.0t GCM) - roughly 30mpg city 16mph avg speed:
The only annoyance was there was no really good way to transport 4x8 sheets. They were a bit heavy for me to get on the roof solo.
Two loader scoops of sand/gravel etc fit in the back of that trailer, same as a regular 6x4 garden trailer. I still use the trailer with the Proton now (no pics yet) and I've used it to tow a 10' trailer to pick up my 8' long tool box.
Not everybody needs to tow light plant on a regular basis. At the end of the day even if you have a Kenworth, there will be times when it's not big enough to transport
something. Overall you're better off just paying the occasional delivery fee.
