I went the other way to offer a first time fix to clients and the ability to do bench work and minor repairs in the van, because not all clients would have a bench and vice I could use.
I went down the Transit Jumbo route, kitted out with a bench, and racking, and I can still get a pallet in the rear or side for big bits of machine, and get long lengths and ladders inside.
I can also change in the van, which also helps depending on the site you are on, some are easier than others.
Mine is exactly what you describe it's a giant roll cab.
You'll start carrying spares once you drop your first couple of nuts and bolts into a pile of swarf never to be seen again, never to be dug out with a magnet coz that just picks up the swarf too, and especially if it's bigger than the nuts and bolts you dropped, you'll never find them.
Just remember that when you are working on machinery itself BS7671 is irrelevant, and there are a lot more recognised standards that are backed up by laws, so you can unwittingly cause a client to end up breaking laws depending on the work you do on the machine, even maintenance wise, that you may not realise.
