Sensai, It does no harm to have a belt and braces approach mate, I found myself in your position this week, my van is knackered but I could carry on working.
I an currently working on my trailer to make it more user friendly for WFP, it's a small box trailer, and I need to fit some kind of rack to the roof to carry my trolley,
I've already fitted the spare wheel carrier to the front of it, just need a trailer that will carry ten containers and all the gear, ideally I want nothing in the car except me and my butties. I am not carrying ladders either, I can leave a set on one estate where I need to access balconies, and a few jobs are going to be dropped.
I can afford to wait until a van pops up at the right price.
I will post a pic when it's complete.
