I swapped trucks with another guy, last week, because he gets better mileage and I was going out of town. I drive a 3/4 ton van stocked to the roof. His is a 3/4 ton truck with a topper and boxes on the sides.
If I always drove his truck, I would turn my phone off. There would be no point taking a service call, unless they only wanted to see my pretty face. You just can't do service work with a little truck.
I get service calls from industrial to commercial to residential and my phone is never off. My co-worker gets his job list in the morning an goes home when he gets to the end of his list. We need different trucks.
So I wonder whether you can do one kind of job in a smaller truck and efficiently get to the other truck when you need it. Do you keep two cordless drills, etc or do you move everything between trucks. Do you have the time to stock both trucks, or will the stock always be on the wrong truck?
I couldn't do it.
