Think twice Adam, having  small van definitely limits you in terms of growth.
I had a transit connect, then branched into softwashing and pressure washing, it was then way too small.
Now got a custom, and it’s just the right size, though even with that, I wish I’d had the LWB. Should have bought the custom before the connect. 
You just never know when you might want to grow/2 man system. 
Always go for the bigger option, the extra room is always handy!
