Not speaking for @Luke, but 1/2 Ton trucks (F-150/Ram1500,etc.) are the norm if not on the smaller side of work vehicles here in the US. I have been amazed at how much stuff @Luke could cram into his 1/4 Ton trucks (the Ranger and Canyon). It’s all about efficient placement of tools and maybe some extra loading and unloading at the beginning and end of each day.
I am far more lazy when it comes to that. Here is my set up:
I’ve got pretty much everything I need in the box of the trailer which is 8’x8’ with the open bed being the same. There’s all my window cleaning equipment, WFP and extensions, pressure washing hoses, wands, screen material rolls for screen enclosures, a 3’x6’ work bench with shelf to do repairs on site, rack & bin system for all of my spare parts, power tools, multi-stage ladders and step ladders, fans for cooling off in the middle of the hot summer days, and a portable toilet for remote work or overnight commercial jobs. All of my tools, with the exception of the extension ladder, are on the trailer. What’s nice about the trailer is that at the end of the day, or week, I can detach it and just use my truck for recreation. My neighborhood does not allow vehicles to have lettering or commercial advertising to be parked in the driveway, so the trailer is backed in behind the fence along the side, and the truck can remain in the driveway.
I never park in a client’s driveway because you never want to be “that guy” that leaves a random oil or fluid stain on the driveway. I always park on the street along the curb when possible. (Except the house depicted since they are set back 150’ from the street, but the pavers are sealed so no worries.)
